--- Comment #3 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
With help of Jakub we managed to figure out that on my setup it is because GCC
5.0 defaults to no .cfi directives, while GCC 4.9 uses them.
This seems to be because cfi working advance test, but we do not see ho this
test changed recently.
It may be helpful to update binutils on tester machines at opensuse.org
