Markus Trippelsdorf <trippels at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|FIXED |--- --- Comment #14 from Markus Trippelsdorf <trippels at gcc dot gnu.org> --- Sorry but the libsanitizer/sanitizer_common/sanitizer_stacktrace.h hunk is missing from your committed patch. So SANITIZER_CAN_FAST_UNWIND is still 0 and the new code in sanitizer_stacktrace.c isn't used at all.
