Additional info:

Comment 1 Dan Horák 2015-11-18 12:21:05 UTC
It's on 32-bit s390 with gcc-5.1.1-4.fc23.s390

Comment 2 Florian Weimer 2015-11-18 12:27:04 UTC
Possible cause: https://sourceware.org/bugzilla/show_bug.cgi?id=19261

I will work around this by disabling -Werror for s390 in rawhide, until we have an upstream fix.
