Crash Data

TEST-UNEXPECTED-FAIL | http://localhost:4444/1277311714515/96/font-face/underline-offset-change-2.html | Exited with code -1073740940 during test run
No stack :(.

Closest thing to it was:
Traceback (most recent call last):
  File "reftest/", line 267, in <module>
  File "reftest/", line 264, in main
    sys.exit(reftest.runTests(args[0], options))
  File "reftest/", line 161, in runTests
    timeout=options.timeout + 30.0)
  File "C:\talos-slave\mozilla-central-w764-opt-u-reftest\build\reftest\", line 770, in runApp
  File "C:\talos-slave\mozilla-central-w764-opt-u-reftest\build\reftest\", line 702, in checkForZombies
    if self.isPidAlive(processPID):
  File "C:\talos-slave\mozilla-central-w764-opt-u-reftest\build\reftest\", line 535, in isPidAlive
    ctypes.windll.kernel32.GetExitCodeProcess(pHandle, self.ctypes.byref(pExitCode))
AttributeError: 'Automation' object has no attribute 'ctypes'

But I don't think that's relevant to the failure.
I can't reproduce this crash on my system with the tinderbox build or my own build.
Turns out this is somewhat intermittent, happens about 50% of the time. I'm running on a test machine and trying to get a stack.
Whiteboard: [orange]
I haven't been able to get a stack on the test machine with windbg. I can't even get it to attach to the process, in fact. When I get back from PTO (next week) i'm going to install it on my mini locally and try with visual studio.
-1073740940 = C0000374 = STATUS_HEAP_CORRUPTION

So, I believe that this is python issue that installed on Tinderbox.

Ben, what version and bit of python on Tinderbox?
We're running the Python 2.5 included with MozillaBuild. It's a 32-bit version.
I don't think this is a crash in Python. The Python traceback you're seeing there is from an unrelated bug (it was fixed in bug 574912). I believe the exit code is actually the Firefox exit code.
When I used Python 2.5 32-bit, I could reproduce this.

Makoto, is there anything I can do to help debug or fix this? I'm a bit lost on the status.

This has already been fixed I believe.  Please reconfirm and comment if you think it has not been fixed, otherwise I think we should resolve this.
I cannot reproduce on current test and this doesn't occurs on tinderbox test.  font code has various changes, so I marked as WFM.
