[Comment 3 Johan Bergström 2014-02-28 22:23:58 UTC]

Do you by any chance have gcc built with IUSE="-mudflap" ?

[Comment 4 Johan Bergström 2014-03-01 04:52:57 UTC]

I rebuilt sys-devel/gcc-4.8.2 with IUSE=mudflap and got the same error. Rebuilt it with IUSE=-mudflap and the error goes away. I've been told that IUSE=mudflap was default since a few weeks back in gentoo which makes a lot of people potentially hitting this bug without rebuilding their GCC. Can someone confirm that they get the same issue/"fix"?

[Comment 5 Steffen Weber 2014-03-02 13:10:03 UTC]

I can confirm that recompiling sys-devel/gcc-4.8.2 with USE=-mudflap fixes the problem.

On another box, recompiling sys-devel/gcc-4.7.3-r1 with USE=-mudflap has fixed the problem, too.

Disable usage of -fmudflapth flag

[Comment 7 Johan Bergström 2014-03-03 22:27:33 UTC]

For history reasons, the rationale behind disabling mudflap altogether is that its deprecated in gcc 4.8 and removed in 4.9. Additionally, upstream should really be moving to -fsanitize if they are interested in similar functionality.
