I happened to be looking at this a while ago, and I already had firefox
with this part commented out:

          CATCH_SIGNAL(SIGILL);
          CATCH_SIGNAL(SIGABRT);
          CATCH_SIGNAL(SIGSEGV);
          CATCH_SIGNAL(SIGTERM);

in toolkit/profile/nsProfileLock.cpp

This makes the backtraces in the core dumps actually useful.

I didn't think to search for the first function in the backtrace on my
previous attempt and gave up. But when I did, I got to the bugzilla bug
report.
