The installation of dev-lang/v8-3.6.6.6 fails because of a segmentation fault, thus preventing chromium from being updated.

I cannot confirm this bug - v8 compiles fine here (quite similar system). Have you run revdep-rebuild to cross check any outstanding problems ? Furthermore, I noticed you have repositories other than gentoo activated. Perhaps this might be the cause ?
PLease attach next time log compile with LC_ALL=C and as attachment
I can't reproduce that either. My French is very bad, so please attach an English build log.
Does replacing "snapshot=${snapshot} \" with "snapshot=no \" in the ebuild fix the problem for you? Note that I assume you know how to create a local overlay and use repoman manifest / ebuild digest.

Switching to gcc-4.6.0 seems to help. I experienced the bug with gcc-4.5.2.
Well, gcc-4.5.2 seems to be a pattern then. It builds fine for me with gcc-4.5.3-r1.
I confirm that it's gcc related. I updated (painfully) gcc to 4.5.3-r1, and v8 just built flawlessly. It would be a good thing to blacklist this version of gcc for this ebuild.
(In reply to comment #8) > I updated (painfully) gcc to 4.5.3-r1 Painful on a quad-core processor? It seems strange to me that you would be using gcc 4.5.2; 4.5.3 has been stable for over a month. Did you have it masked or something? > It would be a good thing to blacklist this version of gcc for this ebuild. I guess we could add DEPEND=">=sys-devel/gcc-4.5.3". Paweł?

(In reply to comment #9) > I guess we could add DEPEND=">=sys-devel/gcc-4.5.3". Paweł? It's not perfect either, one can have 4.5.3 installed but 4.5.2 still active. I think a die hook (similar to www-client/chromium's one) could be better, i.e. check the active gcc version and warn about problems before reporting a bug. Actually if we can, a pkg_pretend check would be even better. We should be able to see the active version of gcc and just call die.
(In reply to comment #11) > Actually if we can, a pkg_pretend check would be even better. We should be able > to see the active version of gcc and just call die. How about this? pkg_pretend() { local gccver=$(gcc-fullversion) if [[ ${gccver} = 4.5.2 ]]; then eerror "The currently selected version of gcc is known to segfault when building this" eerror "version of V8. Please use at least gcc-4.5.3." die "gcc-${gccver} detected" fi }

Please use at least gcc-4.5.3." > die "gcc-${gccver} detected" > fi > } Generally LGTM, one comment: is only 4.5.2 known to cause problems, or older versions are problematic too? In the latter case we could ban everything older than 4.5.3.
I'm not sure if other gcc versions are affected, so I just kept the simple equality check. Added to 3.6.6.5, 3.6.6.6, 3.7.6, and 3.7.7.
