Package: firefox
Version: 48.0-1+b1
Ever since the most recent update, Firefox has crashed, sometimes just a
few seconds after restoring my previous session. The backtrace typically
looks something like this:
(gdb) bt
#0 0x000000000000021d in ?? ()

A similar backtrace was posted in
https://bugzilla.mozilla.org/show_bug.cgi?id=1245783
And also in a couple of Icedove bug reports, though they appear to have
been fixed in 45.2.0-3 with the following comment:
* [a459d6a] debian/rules: adding one more CFLAGS/CXXFLAGS compiler flag
(Closes: #833864, #833532, #833591, #833635, #833698)
Perhaps a similar fix will work in Firefox as well?
