Comment 24 for bug 1322784

https://crash-stats.mozilla.com/report/index/f84c892b-3d01-46f5-aa98-e64d92140501 shows (using minidump_stackwalk):

Thread 0 (crashed)
 0 libxul.so + 0x15ecb6e
    eip = 0xb4bb5b6e esp = 0xbfbf43d0 ebp = 0x8e5ffffe ebx = 0xb6dcaef4
    esi = 0x00000002 edi = 0x82a14014 eax = 0x00000000 ecx = 0xb6dc532a
    edx = 0x00000001 efl = 0x00210282

(didn't get symbols set up)

This is consistent with the disassembly of
http://mirrors.kernel.org/ubuntu/pool/main/f/firefox/firefox_29.0+build1-0ubuntu0.13.10.3_i386.deb
(that's the package for saucy), but not consistent with the disassembly of the Mozilla official Firefox 29 build.
