Description of problem: I found two cores on my system. One 92Megs and another 87Megs. Checking with gdb they were produced this way: warning: Lowest section in system-supplied DSO at 0xffffe000 is .hash at ffffe0b4 Core was generated by `/usr/lib/firefox-2.0.0.4/firefox-bin'. Program terminated with signal 11, Segmentation fault. but there are fingerprints of nsprpub/pr/src/pthreads/ptthread.c and apparently of calls to java in that trace. A trace obtained after installing firefox-debuginfo and nspr-debuginfo is attached. The highest frame I can list is 21 and this looks like that: (gdb) f 21 #21 0xf702e60c in xpc_ThreadDataDtorCB (ptr=0x80ed518) at xpcthreadcontext.cpp:451 451 delete data; Current language: auto; currently c++ (gdb) list 446 PR_STATIC_CALLBACK(void) 447 xpc_ThreadDataDtorCB(void* ptr) 448 { 449 XPCPerThreadData* data = (XPCPerThreadData*) ptr; 450 if(data) 451 delete data; 452 } 453 454 void XPCPerThreadData::MarkAutoRootsBeforeJSFinalize(JSContext* cx) 455 { with 'ptr' as '(void *) 0x80ed518' and '*(XPCPerThreadData*) ptr' coming out as: (gdb) p *(XPCPerThreadData*) ptr $3 = {mJSContextStack = 0x8112be8, mNextThread = 0x0, mCallContext = 0x0, mResolveName = 0, mResolvingWrapper = 0x0, mMostRecentJSContext = 0x9ff5368, mMostRecentXPCContext = 0x8455ce8, mExceptionManager = 0x0, mException = 0x0, mExceptionManagerNotAvailable = 0, mAutoRoots = 0x0, mStackLimit = 4288968920, static gLock = 0x8115830, static gThreads = 0x80ed518, static gTLSIndex = 2} Version-Release number of selected component (if applicable): firefox-2.0.0.4-2.fc7.i386 This is i386 binary running on x86_64 machine. How reproducible: Not really sure but traces from both cores are really the same.

This looks like a dupe of bug 242370...
I agree this is a duplicate of 242370 *** This bug has been marked as a duplicate of 242370 ***

Dammit, my apologies; I was trying to paste that into bug 390901. (I have too many Bugzilla windows open today...)
