--- Comment #3 from Jim Wilson <wilson at gcc dot gnu.org> --- I did a cross compiler build and check yesterday using up-to-date sources and did not see this failure. I've been testing regularly. I did my build on an x86_64 Ubuntu 16.04 machine with gcc-5.4 as the system compiler. Maybe this depends on the compiler used for the build? Or the exact configure command?
