--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 40135 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40135&action=edit gcc7-pr78482-test.patch Does this patch fix that? In addition to changing char to signed char, I've changed the testcase so that it actually FAILs with unfixed compiler and PASSes with fixed one, previously with unfixed compiler it would just print 2 on stdout where nothing would notice that.
