 // If AddressSanitizer is used, NULL pointer dereferences generate SIGILL
 // (illegal instruction) instead of SIGSEGV (segmentation fault).  Also,
 // the number of memory regions differs, so there is no point in running
 // this test if AddressSanitizer is used.
 //
 // Ideally we'd use this attribute to disable ASAN on a per-func basis,
 // but this doesn't seem to actually work, and it's changed names over
 // time.  So just stick with disabling the actual tests.
