Details
Seems like this could be due to something corrupting memory somewhere since I've seen the wierdest stack traces when trying to debug this, some that don't make any sence at all! One possible problem could be that the frame hash in the frame manager (or some other code that maps content to frames) isn't for some reason in sync with existsing frames (I'm not sure at all about this). From what I can tell from the stack trace below the frame hash might have something to do with this (thus I'm cc'ing troy since he wrote the frame hash if I recall correctly). But then again this might be a bogus stack trace so don't take it too seriously. Program received signal SIGSEGV, Segmentation fault. 0x40dc4cc4 in nsCSSFrameConstructor::ContentChanged (this=0x82abdf8, aPresContext=0x8291fc0, aContent=0x8737978, aSubContent=0x0) at nsCSSFrameConstructor.cpp:6691 6691 frame->ContentChanged(aPresContext, aContent, aSubContent); ^^^^^-comes from shell->GetPrimaryFrameFor(...) (gdb) bt 10 #0 0x40dc4cc4 in nsCSSFrameConstructor::ContentChanged (this=0x82abdf8, aPresContext=0x8291fc0, aContent=0x8737978, aSubContent=0x0) at nsCSSFrameConstructor.cpp:6691 #1 0x40eacee1 in StyleSetImpl::ContentChanged (this=0x82abdb0, aPresContext=0x8291fc0, aContent=0x8737978, aSubContent=0x0) at nsStyleSet.cpp:903 #2 0x40cb6e0e in PresShell::ContentChanged (this=0x82abe40, aDocument=0x8281560, aContent=0x8737978, aSubContent=0x0) at nsPresShell.cpp:1693 #3 0x4088f151 in XULDocumentImpl::ContentChanged (this=0x8281560, aContent=0x8737978, aSubContent=0x0) at nsXULDocument.cpp:1683 ... (gdb) print frame $20 = (nsIFrame *) 0x87cfe00 (gdb) print *frame $21 = {<nsISupports> = {_vptr. = 0x0}, } I'll continue investigating, If anyone has some input let me know...
