Seems to coincide with http://pkgs.fedoraproject.org/cgit/rpms/golang.git/commit/?h=f24&id=7e3e63c06c2964ddda1a7c801798eeabe1762ac5
Version-Release number of selected component (if applicable):
I have looked in to it and as fix I have made the patch(introduced in 7e3e63c06c2964ddda1a7c801798eeabe1762ac5) not apply(as there are no significant benefits of it) on ppc64(le), as it slightly increases stack usage resulting in nosplit stack overflow there. Build on the way.
