--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 43911 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43911&action=edit gcc8-pr85342.patch Untested fix. After failed apply_change_group, recog_data.insn is NULL and rest of recog_data is garbage, so there is no need to update it.
