1055231 - Jetpack tests don't properly symbolize XUL crashes

Status: RESOLVED DUPLICATE of bug 873204

(Testing :: General, defect)

Description

[Andrew McCreight [:mccr8]]

With a patch I wrote that intentionally crashes in jemalloc, the Jetpack test suite does not produce a useful crash stack:

Hit MOZ_CRASH() at /builds/slave/try-l64-d-00000000000000000000/build/memory/mozjemalloc/jemalloc.c:1572

Program firefox/firefox-bin (pid = 1790) received signal 11.

Presumably this isn't a big deal mostly, because other tests should catch libxul crashes, but I thought I'd file it anyways.  (This doesn't affect me because I wrote a patch that just crashes everywhere, so this is presumably an instance of that other issue.)
