This is not the case. Not sure what guarantees D's checked memory provides but ASan doesn't offer protection from uninitialized reads. MSan, does, though. Plus: none of the sanitizers offer quite-the-same runtime protections. They're intended for use in testing to flush out bugs, not production for avoiding bugs. As is, MSan and ASan are mutually exclusive.
