Details

I ran purify. During the session, I loaded the first 6 sample documents in viewer, and http://www.starwave.com. I don't know which page triggered this. Could it be related to cache problems we've been seeing? ================ report ================== [W] UMC: Uninitialized memory copy in memcpy {23 occurrences} Copying 4 bytes from 0x0584b45c (4 bytes at 0x0584b45c uninitialized) Address 0x0584b45c is 44 bytes into a 88 byte block at 0x0584b430 Address 0x0584b45c points to a C++ new block in heap 0x04320000 Thread ID: 0x70 Error location memcpy [memcpy.asm:110] nsCacheObject::Info(void)const [nsCacheObject.cpp:396] nsDiskModule::AddObject(nsCacheObject *) [nsDiskModule.cpp:157] CacheObject_Synch [CacheStubs.cpp:353] net_CacheComplete [mkcache.c:1479] net_ProcessHTTP [mkhttp.c:3522] NET_ProcessNet [mkgeturl.c:3366] NET_PollSockets [mkselect.c:320] NetlibTimerProc(void *,UINT,UINT,DWORD) [nsNetThread.cpp:257] TranslateMessageEx [user32.dll] Allocation location new(UINT) [new.cpp:23] CacheObject_Create [CacheStubs.cpp:96] NET_CacheConverter [mkcache.c:1770] NET_StreamBuilder [mkstream.c:243] net_setup_http_stream [mkhttp.c:2805] net_ProcessHTTP [mkhttp.c:3476] NET_ProcessNet [mkgeturl.c:3366] NET_PollSockets [mkselect.c:320] NetlibTimerProc(void *,UINT,UINT,DWORD) [nsNetThread.cpp:257] TranslateMessageEx [user32.dll]

Steve, can you run these URL's thru Purify again and see if the UMC is gone? If so, please mark verified. Muchos gracias.

will mark verified if reporter agrees with fix
Status: RESOLVED → VERIFIED
Changing all Networking Library/Browser bugs to Networking-Core component for Browser. Occasionally, Bugzilla will burp and cause Verified bugs to reopen when I do this in a bulk change. If this happens, I will fix. ;-)
Bulk move of all Networking-Core (to be deleted component) bugs to new Networking component.
