Package built successfully; Portage elog warning asked me to file a bug. 3. Bug report filed. :) Actual Results: I'm going to attempt to execute the browser; try it out, surf the web, see if I like it, etc... possibly unmerge it... Expected Results: Not being asked to file a bug. ;) No big deal, though. Gentoo rocks; you guys are doing awesome! I'm running the following profile: /usr/portage/profiles/default/linux/amd64/10.0/desktop/ And I like Gentoo. And cheese.

Thanks for the report! In fact you have two bugs in one here: one on RWX sections in chrome binary, another where it crashes at start As you are on stable amd64, do you by any chance use nvidia binary drivers? Then the crash is bug #295756 Let's keep this bug open for the exec stack problem, I recall there were such warnings when getting chromium in portage, but they were fixed... Obviously they're back!
Hey there. Yes, I do use the (stable) nvidia binary drivers. Thanks for pointing out bug 295756 (I searched before posting, but didn't yet have the segfault issue). I may try using the latest (testing) version of the drivers, as that seemed to work for a user there. Thanks again. -brant

Pawel, can you take care of sending this upstream? http://www.gentoo.org/proj/en/hardened/gnu-stack.xml#doc_chap6
I think 4.0.288.1 was okay... Please reopen if that's not the case.
Ooops, no. Still there in 4.0.295.0. Will report upstream right now.
