--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I guess on Linux nothing ever calls __cxa_rethrow_primary_exception, so it isn't a big deal that libasan provides a wrapper for it. If you want to introduce ASAN_HAS_CXA_RETHROW_PRIMARY_EXCEPTION, it would need to be introduced some way that either it would default to 1 and gcc/libsanitizer/asan/Makefile.in was able to override it, so e.g. #ifndef ASAN_HAS_CXA_RETHROW_PRIMARY_EXCEPTION # define ASAN_HAS_CXA_RETHROW_PRIMARY_EXCEPTION 1 #endif in say asan/asan_internal.h and add -DASAN_HAS_CXA_RETHROW_PRIMARY_EXCEPTION=0 to libsanitizer/asan/Makefile.*.
