--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 53923 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53923&action=edit gcc13-pr107748-uglify.patch Besides the missing uglification in this spot, I found some others (only checked for . followed by [a-zA-Z] and grepped away what happens usually in comments, #include/#error lines etc.). Will test tonight.
