--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Created attachment 34666 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=34666&action=edit Patch I am testing. The following patch fixes the parameters, but I do not get any ubsan_unreachable calls. Jakub, can you take a look, please?
