--- Comment #7 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- I have run memcmp-1.exe under lldb trying various break points from line 1 to 12 and I always get Process 45744 launched: '/Users/dominiq/Documents/Fortran/g95bench/win/f90/bug/memcmp-1.exe' (x86_64) ==45744==AddressSanitizer CHECK failed: ../../../../5_work/libsanitizer/asan/asan_malloc_mac.cc:103 "((!asan_init_is_running)) != (0)" (0x0, 0x0) <empty stack> Process 45744 exited with status = 1 (0x00000001) without any backtrace available. > Le 11 janv. 2016 à 17:20, chefmax at gcc dot gnu.org > <gcc-bugzi...@gcc.gnu.org> a écrit : > > https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69147 > > --- Comment #6 from Maxim Ostapenko <chefmax at gcc dot gnu.org> --- > Ok, it seems that libasan calls some function to be intercepted while > AsanInitInternal still not completed.
