Mozilla-firefox-0.9.1 previously compiled succesfully on my system, and after a few updates no longer compiles. Updates included gcc and glibc. Exited due to a segmentation fault in gcc. the error, preprocessed source, and emerge info are attached.

The problem here is that mozilla-firefox isn't stripping flags like mozilla and mozilla-thunderbird. I'll fix it.
Added note: This is now also occuring with version 9.3
Right, sorry I didn't get it fixed in time for the 0.9.3 bump. I've been working non-stop on moz/ff/tb the past couple of days and this fix is in my local builds.
It's still not compiling for 1.0_pre.
I believe this is fixed, at least in the current version 1.0-r1. Please open a new bug if you see the problem on current versions.
