771920 - Debug builds unusable on mac due to write poisoning

Status: RESOLVED DUPLICATE of bug 771083

(Core :: XPCOM, defect)

Description

[Boris Zbarsky [:bzbarsky]]

I had a debug build crash.  Now every time I start it, the following things happen:

1)  WARNING: Last startup was detected as a crash.: 
    file ../../../../mozilla/toolkit/components/startup/nsAppStartup.cpp,
    line 942
2)  ###!!! ASSERTION: consider quit stopper out of bounds:
    'mConsiderQuitStopper > 0', file 
    ../../../../mozilla/toolkit/components/startup/nsAppStartup.cpp, line 533
3)  Process shuts down (why?  who knows)
4)  WARNING: XPCOM objects created/destroyed from static ctor/dtor:
    file ../../../mozilla/xpcom/base/nsTraceRefcntImpl.cpp, line 141 several
    times
5)  Assertion failure: r == count, at
    ../../../mozilla/xpcom/build/mozPoisonWriteMac.cpp:194

#5 of course crashes the process, so the next time around the same exact things happens.  Result: I can't start the build at all.

I _think_ steps 1-4 were preexisting, but step 5 was added in bug 732173 and makes it completely impossible to use the build.

The stack to #5 is:
