--- Comment #3 from Will Schmidt <willschm at gcc dot gnu.org> --- (In reply to seurer from comment #1) > In addition to trunk this also fails with gcc 7 Yup. There was/is an ice in one of the builtins-3.* tests that should be better now , per https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84422#c1 it is in my queue to re-check the results, and possibly loosen up the requires or options on one of the tests. I'll pursue a backport to gcc7 after I check that over.
