[Bug 1471949] [NEW] Firefox 39 crashes on startup or within a few seconds on Precise/x86

[Chris Coulson]

Public bug reported:

This is blocking publication of Firefox 39.

The build for x86 on 12.04 currently crashes on startup, or within a few
seconds of startup. It's basically unusable. An example crash report is:
https://crash-stats.mozilla.com/report/index/d0d97dbb-f6bc-4e4d-88ff-
e5fff2150702.

Unfortunately, despite the warning in the PPA description for
https://launchpad.net/~ubuntu-mozilla-security/+archive/ubuntu/ppa,
ordinary users are still installing pre-release packages from it.

It works on all other releases and on Precise/x86-64. I did test Firefox
39 with this toolchain when it was still the nightly version whilst
preparing the switch to GCC 4.8, and it worked fine.
