I don&#x27;t know of any large, widely used, security critical, heavily scrutinized C++ program that uses those flags in production. I also don&#x27;t know of any such C++ program that hasn&#x27;t had game-over use after free bugs. So the answer to your question is somewhere ranging from &quot;we don&#x27;t know, but unlikely&quot; to &quot;no&quot;.
