--- Comment #4 from Bernd Schmidt <bernds at gcc dot gnu.org> --- Created attachment 37906 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=37906&action=edit Candidate patch Jakub, if you have a machine to test this on, can you try this patch? It's probably not the full patch I'll submit, but it should cure this particular issue.
