Thanks to Cănărău Constantin for reporting and the patch from Fedora, and
Rafał Mużyło for the patch from upstream.  With the patch from upstream applied
in x11-base/xorg-server-1.17.1-r1 it builds fine with gcc 5.1.0.

Comment 5 Joe Kappus 2015-05-05 05:40:54 UTC

That patch works but you still need to build without graphite optimization or a fail will occur.

I only get the build failure with graphite loop optimizations if I use the "-flto" or "-O3" flags.

My flags for building xorg-server right now are "-march=native -pipe -O2 -fgraphite-identity -floop-interchange -floop-strip-mine -floop-block", which work.
