From initial report here: https://bugzilla.mozilla.org/show_bug.cgi?id=518634#c0

Unittests on an optimized Linux builds crashed.  We got a stack trace, but without symbols.

I suggested that we should grab one of these builds + associated symbols, unpack them somewhere, run the browser, kill it to get a minidump, and try running minidump_stackwalk with that dump + the symbols to sanity check that it works.

I tried this locally and the stack trace came out with symbols. I grabbed the build + symbols from this build:
http://tinderbox.mozilla.org/showlog.cgi?tree=Firefox-Unittest&errorparser=unittest&logfile=1254150797.1254152377.1343.gz&buildtime=1254150797&buildname=Linux%20mozilla-central%20test%20opt%20mochitests&fulltext=1

Which had a crash and displayed a stack trace without symbols. It looks like the symbols are unpacked in the right place, and the runtests.py commandline references them properly. I'm not sure what's going on here.

I'm seeing this on regular unittest builds too:
http://tinderbox.mozilla.org/showlog.cgi?tree=Firefox-Unittest&errorparser=unittest&logfile=1254313915.1254316010.3374.gz&buildtime=1254313915&buildname=Linux%20mozilla-central%20test%20everythingelse&fulltext=1

I think there's a deeper problem here.

I'm not sure how this ever worked, honestly, but I pushed a fix:
http://hg.mozilla.org/mozilla-central/rev/0f0239688a76
(I also left in some extra debug output in there, to give more info in case MINIDUMP_STACKWALK isn't set.)

I was able to reproduce the problem locally using a build+packaged tests, and this patch fixed it.
