Backtrace

The browser window opens for a second, and then closes due to a segfault.

See attached backtrace. Based on this and some strace logging, it looks like it crashes when it tries to install the default set of extensions on the initial profile creation.

I'm making a guess that this is related to the C++11 ABI changes in GCC 5.1.0.

phajdan.jr: Can you take a look before I file a bug upstream? I'm not sure if there is other useful info I can provide upfront.
Comment 1 Mike Gilbert gentoo-dev 2015-05-31 03:38:26 UTC 
I should also add that running chromium with --disable-extensions seems to keep it from crashing.

I'd recommend just filing the upstream bug. Please make sure to include the version of Chrome and post the link to the bug here.
Comment 3 Mike Gilbert gentoo-dev 2015-05-31 17:18:45 UTC 
I opened an issue upstream, link in URL.

Known issue, already fixed in gcc:

Comment 5 Mike Gilbert gentoo-dev 2015-06-03 20:03:29 UTC 
Thanks for that.
Comment 6 Mike Gilbert gentoo-dev 2015-06-04 02:16:31 UTC 
After applying the patch from gcc upstream, chromium work again. Thanks!
Comment 7 Ryan Hill (RETIRED) gentoo-dev 2015-06-07 02:02:14 UTC 
Removed porting blocker because this is a GCC issue.
Comment 8 Alexey Shvetsov archtester gentoo-dev 2015-06-19 12:36:43 UTC 
I cannot even compile chromium-44.0.2403.xx with gcc-5.1.0
Comment 9 Ryan Hill (RETIRED) gentoo-dev 2015-06-19 23:40:00 UTC 
Probably bug #548412.

No. #548412 is a build error. This bug is a wrong code issue.
Comment 11 Ryan Hill (RETIRED) gentoo-dev 2015-07-07 04:01:11 UTC 
I was referring to comment #8.
Comment 12 Ryan Hill (RETIRED) gentoo-dev 2015-07-18 05:23:26 UTC 
This should be fixed with gcc-5.2.0.
