Christophe Lyon <clyon at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |clyon at gcc dot gnu.org --- Comment #18 from Christophe Lyon <clyon at gcc dot gnu.org> --- Hi, I'm seeing random results on: c-c++-common/Wstringop-truncation.c -Wc++-compat (test for warnings, line 210) c-c++-common/Wstringop-truncation.c -Wc++-compat (test for warnings, line 211) on aarch64/arm targets if that matters. By random, I mean sometimes these two tests pass, sometimes they fail. May it mean that the patch (r254630) has an undefined behavior code path?
