Created attachment 410930 [details]
emerge --info + build.log

[Comment 2 Bernard Cafarelli 2015-09-03 15:41:36 UTC]

My bet is on a GCC5 specific error, can you test with the patch from:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=777779 ?

[Comment 3 Alexandre Rostovtsev (RETIRED) 2015-09-04 00:58:21 UTC]

You are right.

Builds fine with gcc-4.9.2 out of the box.

Builds fine with gcc-5.2.0 + patch from https://bugs.debian.org/cgi-bin/bugreport.cgi?filename=30_gcc5.patch;bug=777779;att=1;msg=21

[Comment 4 Bernard Cafarelli 2015-09-04 11:49:24 UTC]

OK :) Patch added to current ebuild
