I have reviewed two similar bugs but this does not appear to match either. Firefox seems to segfault trying to access a sqlite file in the user profile (based on my very limited ability to understand strace output, which I have attached).

Sorry about the duplication (both bugs and attachments, it seems). Some sort of browser mishap.
Confirmed here, even I suspect something related to gtk+, as is the only upgrade that I can think of tha can be had some effects since I've noticed the issue. Investigating...
I have a similar issue with mozilla-firefox-3.5.2-r3, mozilla-firefox-3.5.3 and even with mozilla-firefox-bin-3.5.3. After reinstalling whole world with gcc-4.4.1 -O3, all the foxes segfault upon start before showing the window. I guess it is specific for x86, for amd64 seems ok, but I am not 100 % sure. The problem is with zlib (in my case 1.2.3-r1) when compiled with gcc-4.4.1 -O3. Just recompiling zlib with either gcc-4.3.4 -O3 or gcc-4.4.1 -O2 fixes the problem and I can enjoy the "Thank you for downloading Firefox" video :) In particular, the tree-vectorize optimization causes the bug, hence zlib still compiles fine even with CFLAGS="... -O3 -fno-tree-vectorize ...". Maybe this helps, but probably it is a different issue. I can see -O2 in your CFLAGS, but you may have compiled zlib with -O3 earlier (???). You also mention sqlite based on strace observation. Try >=mozilla-firefox-3.5.2-r2 (with >=xulrunner-1.9.1.2-r2), they now use internal bundled sqlite instead of the system one. You can also try just simply running /usr/lib/mozilla-firefox/firefox in gdb and wait for the crash. Even with minimal debug information you may see the library where the segfault appears. So should I file a separate bug report concerning firefox and zlib?
Ok, I just got more crashes, this time caused by fontconfig-2.7.3 in exactly the same way as with zlib. Again the same solution (-O2 or -fno-tree-vectorize), tree-vectorize is really bitch on x86!
This is likely a gcc-4.4 bug with x86 + -fforce-addr For gcc-4.4 + x86 + -ftree-vectorise, see bug 270120
No, I've always had -O2 on that machine. I will remove -fforce-addr and rebuild.

Please do not close, we either need to filter it via the ebuilds are explode in portage.
you would have to filter flags in half a dozen ebuilds (that we know of). just don't use -ftree-vectorize on x86 until bug #270120 is fixed. yeah it's a pain in the ass.

Closing!!!
