This reminds me of bug 79562, also involving the MIPSpro compiler on IRIX. cc'ing Brendan, zeroJ@null.net for advice. Does this look like the same problem?

CC -version MIPSpro Compilers: Version 7.2.13m Crash occurs consistently on startup. I have compiled it only with default options.

Ryan ... could you indicate what configure flags you are using ... I have a 0.9 build I can test on. Initially I would guess the problem is with your compiler version ... we have only been using 7.3.1.?m. We have every engr release of the compiler on CDs so I should be able to help you out on this one ... however you will do better with a gcc build at the moment until I get a fix for bug 79562. You can optimise gcc to -O6 with only occasional core dumps after extended use.

I have been using configure with no flags, just the basic ./configure; make I'll try it with the 7.30 mips compilers.

Since you have a build using older compilers than we have tried, could I impose on you to try only building the module js with MIPSpro 7.3.*, and revert back to the older compiler to continue the build ... this way we can determine if using MIPSpro 7.2 only fails in js, in which case I will ask my manager at SGI if I can dedicate a bit of time to getting the js module to work using the older compilers which many customers will still have installed. I dont know how easy this is ... if its too much trouble dont bother ... gcc builds are faster atm anyhow.

I've just had a chat with Robert Low, the previous maintainer of the IRIX port, and he pointed out bug 30427 which was solved with -OPT:wn_simplify=off . Perhaps you could give that a go.

I am not so sure that the keyword crash is appropriate, as this is occuring on an unsupported compiler version.

Of course, it won't let me build with the 7.30 compilers: gmake[3]: Entering directory `/export/data/atm/hankins/mozilla/dom/src/base' nsJSEnvironment.cpp Building deps for nsJSEnvironment.cpp CC -o nsJSEnvironment.o -c -DOSTYPE=\"IRIX6\" -DOSARCH=\"IRIX\" -DMOZ_REFLOW_PERF -DMOZ_REFLOW_PERF_DSP -DOJI -D_IMPL_NS_DOM -I../../../dist/include -I../../../dist/include -I/hosts/clink/data/clink/atm/hankins/mozilla/dist/include/nspr -KPIC -woff 3262 -n32 -DDEBUG -DDEBUG_hankins -DTRACING -g -I./../build -DMOZILLA_CLIENT -DIRIX=1 -DNSCAP_DISABLE_DEBUG_PTR_TYPES=1 -DD_INO=d_ino -DMOZ_WIDGET_GTK=1 -DMOZ_ENABLE_XREMOTE=1 -DMOZ_DEFAULT_TOOLKIT=\"gtk\" -DMOZ_X11=1 -DSTDC_HEADERS=1 -DHAVE_ST_BLKSIZE=1 -DHAVE_INT16_T=1 -DHAVE_INT32_T=1 -DHAVE_INT64_T=1 -DHAVE_UINT=1 -DHAVE_UINT_T=1 -DHAVE_UINT16_T=1 -DHAVE_DIRENT_H=1 -DHAVE_GETOPT_H=1 -DHAVE_MEMORY_H=1 -DHAVE_UNISTD_H=1 -DHAVE_SYS_FILIO_H=1 -DHAVE_NL_TYPES_H=1 -DHAVE_SYS_STATVFS_H=1 -DHAVE_SYS_STATFS_H=1 -DHAVE_SYS_VFS_H=1 -DHAVE_SYS_MOUNT_H=1 -DHAVE_SYS_CDEFS_H=1 -DHAVE_LIBM=1 -DHAVE_LIBDL=1 -DHAVE_LIBSOCKET=1 -DHAVE_RANDOM=1 -DHAVE_QSORT=1 -DHAVE_STRERROR=1 -DHAVE_LCHOWN=1 -DHAVE_FCHMOD=1 -DHAVE_SNPRINTF=1 -DHAVE_LOCALTIME_R=1 -DHAVE_STATVFS=1 -DHAVE_MEMMOVE=1 -DHAVE_USLEEP=1 -DHAVE_RINT=1 -DHAVE_NL_LANGINFO=1 -DHAVE_GETTIMEOFDAY=1 -DGETTIMEOFDAY_TWO_ARGS=1 -DHAVE_DEV_ZERO=1 -DHAVE_SYSERRLIST=1 -DHAVE_OSTREAM=1 -DHAVE_CPP_EXPLICIT=1 -DHAVE_CPP_SPECIALIZATION=1 -DHAVE_CPP_MODERN_SPECIALIZE_TEMPLATE_SYNTAX=1 -DHAVE_CPP_PARTIAL_SPECIALIZATION=1 -DHAVE_CPP_ACCESS_CHANGING_USING=1 -DHAVE_CPP_AMBIGUITY_RESOLVING_USING=1 -DHAVE_CPP_NAMESPACE_STD=1 -DHAVE_CPP_UNAMBIGUOUS_STD_NOTEQUAL=1 -DHAVE_CPP_NEW_CASTS=1 -DHAVE_CPP_DYNAMIC_CAST_TO_VOID_PTR=1 -DNEED_CPP_UNUSED_IMPLEMENTATIONS=1 -DHAVE_I18N_LC_MESSAGES=1 -DMOZ_LOGGING=1 -DMOZ_MAIL_NEWS=1 -DMOZ_EDITOR_API_LOG=1 -DMOZ_ENDER_LITE=1 -DNS_MT_SUPPORTED=1 -DIBMBIDI=1 -DDETECT_WEBSHELL_LEAKS=1 -DMOZ_USER_DIR=\".mozilla\" -DMOZ_XUL=1 -DINCLUDE_XUL=1 -DMOZ_XSL=1 -DMOZ_NEW_CACHE=1 -DUSE_IMG2=1 -DMOZ_DLL_SUFFIX=\".so\" -DXP_UNIX=1 -DUNIX_ASYNC_DNS=1 -DHAVE_MOVEMAIL=1 -DJS_THREADSAFE=1 nsJSEnvironment.cpp "nsJSEnvironment.cpp": Error: A goto outside a region cannot jump to a label inside a region, 1 at line 369 gmake[3]: *** [nsJSEnvironment.o] Error 2 gmake[3]: Leaving directory `/export/data/atm/hankins/mozilla/dom/src/base' gmake[2]: *** [install] Error 2 gmake[2]: Leaving directory `/export/data/atm/hankins/mozilla/dom/src' gmake[1]: *** [install] Error 2 gmake[1]: Leaving directory `/export/data/atm/hankins/mozilla/dom' gmake: *** [install] Error 2 [hankins@clink mozilla]$ CC -version MIPSpro Compilers: Version 7.30 I suppose that might be a topic for a different bug...

I get the same dump when I compile everything with 7.30 compilers, after commenting out those two lines that cause the compilation to fail.

Our approach to date has been to only use/support the latest engr release of MIPSpro ... as Mozilla has consistently created new MIPSpro optimisation bugs. I have done one workaround where it was simple ... and it looks like one is possible for bug 79562, which looks too similar to this one, as JS_ARENA_ALLOCATE_TYPE is #defined in js/src/jsarena.h to use JS_ARENA_ALLOCATE_CAST.

-OPT:wn_simplify=off fixes the problem, eliminating the segfault. Can that be added to the makefiles for the MIPSpro compilers (if gcc isn't found on an IRIX box, use that option?)

http://support.sgi.com/colls/patches/tools/relstream/index.html is the link given by var@sgi.com, in the bug 30427 that this report duplicates, as the place to go to upgrade your busted MIPSPro compiler to a fixed version. /be *** This bug has been marked as a duplicate of 30427 ***

Ahem. Caffeine-enabled, I've read this bug now, and related bugs, and want to apologize for mad dup'ing. If this bug should be reopened, please do so and say what fix someone responsible for the JS engine needs to make -- or reassign to a better owner. Sorry again. /be

Reassigning to build config, since this should really be fixed there. It would be nice to check for old compilers, and not gcc, and IRIX, and if we have all of those, to enable that particular compiler flag. Also going to drop priority.

Setting default owner and QA -

Ok, so here's the interesting part....cement, the Irix tinderbox on the SeaMonkey-Ports page, is using MIPSPro Version 7.2.1.3m and appears to have no problems starting up or running the tinderbox tests. The Irix nightlies are also created on that box. So we have conflicting sets of data here. Ryan, can you run the nightlies builds where your custom builds fail? Also, can you provide the complete set of configure options and commands that you used to create your custom builds?

Nightly builds work just fine for me. I'm typing this using 2001062821. To compile the source releases that crash, I just do a ./configure, then a gmake. I've used 7.2.1.3m, and 7.30 release compilers, and they both seem to cause this crash. I was under the impression that the nightly builds were gcc builds.

Nope, the nightly builds are definitely using cc & CC to build. Do you see the crash in your custom build if you use ./configure --disable-debug --enable-optimize ? If you are going to use the 7.3 series of the compiler, I definitely recommend using the latest version of that series (7.3.1.2).

./configure --disable-debug --enable-optimize on the 7.30 compilers crashes. I'll try with the new compilers when I get a chance.

$ cc -version MIPSpro Compilers: Version 7.3.1.2m $ CC -version MIPSpro Compilers: Version 7.3.1.2m Crashes on startup just like the others.

I'm not convinced that this is a general Irix compiler problem since so far, no one has been able to reproduce the problem. I can't find any reference to 'wn_simplify' in the opt manpage. What exactly does -OPT:wn_simplify=off do?

Chris, -OPT:wn_simply=OFF turns off the simplifier, which can be seen to cause the problem in bug 30427. I can only reproduce these js problems with --disable- debug ... does cement --disable-debug? Ryan, Before I make changes to any Makefile.in's ... can you attach the diff of the modifications you made to remove the goto ... and verify that it was MIPSpro 7.30 with -OPT:wn_simplify=off which builds and runs.

No, the cement tinderbox build does not use --disable-debug but the Irix nightly builds that come from cement do use --disable-debug . I'll move cement to doing an optimized build to see if it make a difference.

Sounds good. Do the nightly builds also undergo tinderbox tests before they are deemed fit for the public?

Nope. They are just built and packaged.

Sorry about the delay; I have been away and very busy. Anyway, it was definitely MIPSPro 7.30 with -OPT:wn_simplify=off. To remove that goto, I just commented out the two offending lines as a quick fix, assuming that it was an error condition that wouldn't occur normally. Obviously it needs a better fix than that.

This works fine in 0.9.3, with the same compilers and everything. Suggest this bug be closed.

resolving WFM per reporter's comments.

verifying, same.
