Jiu Fu Guo <guojiufu at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |guojiufu at gcc dot gnu.org --- Comment #9 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> --- The latest trunk has fixed this issue. As check the fix is r11-321 998fbe9f1f7e5ef53ca79fbd28f8a3875a477baa. This fix is handling the debug_insn which was also mentioned in comment 4. Just wondering if need to backport to gcc10/9.
