I discovered this evening the bug which I believe has been the cause of the PLT failures for the last several days. (Chris has not been able to get results since 2/10). I ran this command: run-plt --leave-prefs "activate; run cvs-base; emptyCache; clearHistory; wait 30; run cvs-base; wait 10; run cvs-base; wait 10; run cvs-base; wait 10; run cvs-base; wait 10; run cvs-base; wait 10; run cvs-base" and caught Safari dying in the debugger: Program received signal SIGABRT, Aborted. 0x9004714c in kill () (gdb) bt #0 0x9004714c in kill () #1 0x90128b98 in abort () #2 0x946f3eb4 in __gnu_cxx::__verbose_terminate_handler () #3 0x946f1a54 in __cxxabiv1::__terminate () #4 0x946f1ab8 in std::terminate () #5 0x946f2164 in __cxa_pure_virtual () #6 0x01e6b7e4 in WebCore::TimerBase::fireTimers (fireTime=1140060708.2481711, firingTimers=@0xbfffe238) at /Build/Safari-TOT/OpenSource/WebCore/platform/Timer.cpp:333 #7 0x01e6b890 in WebCore::TimerBase::sharedTimerFired () at /Build/Safari-TOT/OpenSource/WebCore/platform/Timer.cpp:350 #8 0x90770aec in __CFRunLoopDoTimer () #9 0x9075d464 in __CFRunLoopRun () #10 0x9075ca18 in CFRunLoopRunSpecific () #11 0x9318f1e0 in RunCurrentEventLoopInMode () #12 0x9318e874 in ReceiveNextEventCommon () #13 0x9318e6e0 in BlockUntilNextEventMatchingListInMode () #14 0x9368d104 in _DPSNextEvent () #15 0x9368cdc8 in -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] () #16 0x0001c324 in -[BrowserApplication nextEventMatchingMask:untilDate:inMode:dequeue:] (self=0xf11d690, _cmd=0x0, mask=4294967295, expiration=0xf1720e0, mode=0x2d, dequeue=1 '\001') at /Build/Safari-TOT/Internal/WebBrowser/BrowserApplication.m:152 #17 0x9368930c in -[NSApplication run] () #18 0x93779e68 in NSApplicationMain () #19 0x00003114 in _start (argc=3, argv=0xbffff5b0, envp=0xbffff5c0) at /SourceCache/Csu/Csu-58/crt.c:272 #20 0x00002fbc in start () This bug seems to only reproduce with TOT Safari (and thus has not been affecting the PLT slave... I don't think.)

Might have been fixed in bug 7274.

A call to a pure virtual method wouldn't compile, so I suspect it's the result of a corrupted vtable, in turn the result of a prematurely deallocated object. MallocScribble or, if you have a few years, libgmalloc, may help track this down.

Seems like this might be a dup of bug 7274.

Eric, is this still happening after the fix for bug 7274 or not?
