================
Comment at: lib/sanitizer_common/sanitizer_malloc_mac.inc:75
+    if (malloc_num_zones > 1 && malloc_zones[0] != &sanitizer_zone) {
+      for (unsigned i = 0; i < malloc_num_zones; i++) {
+        if (malloc_zones[i] == &sanitizer_zone) {
----------------
Iteration should start with 1 since the condition will always be false for i==0. The current version is correct, but was a bit more complicated to reason about since the intention is never to malloc_zones[0] with malloc_zones[0].
