I've tried emerging several versions of the Mozilla Firefox and none worked. Everyone died segfaulting. I removed .mozilla/ dir just in case everytime I tried to run it. Currently I've installed www-client/mozilla-firefox-1.5.0.3 (tried older too, and yes, I've tried with the binary ebuild). When I run '/usr/lib/mozilla-firefox/firefox-bin' and try to open slashdot.org it dies after a few seconds arguing a segmentation fault. 'echo $?' says '139' (always the same error number). The Mozilla Suite also presents random crashes but I couldn't manage to reproduce it. I have this relevant packages installed: www-client/mozilla-launcher-1.51 www-client/mozilla-firefox-1.5.0.3 www-client/mozilla-1.7.13 net-libs/gecko-sdk-1.7.13 I recompiled mozilla-firefox after upgrading the mozilla suite (and gecko-sdk).

That's what you usually get when using insane C[XX]FLAGS. :P
Tone down the CFLAGS and CXXFLAGS and then open a bug until then you want to live on the edge you are on your own.

(In reply to comment #2) > Tone down the CFLAGS and CXXFLAGS and then open a bug until then you want to > live on the edge you are on your own. Firefox was compiled with very conservative flags (-O2 -pipe), I assume you mean I have to tone down the flags of my whole system. What would you recommend? I've seen that firefox's ebuild add's visibility stuff which I thougt was more risky than mine.
