`gcc` still as bugs. `clang` still has bugs. There was one recently on HN where one pass in clang caused undefined behavior in another. Are these not yet ready for prime time?<p>Furthermore, this is a known bug, and not too high priority probably since it&#x27;s pretty rare to stack allocate something huge and then use it in a way that could cause a vulnerability (instead of crashing). The fix would involve replacing the segfault with a stack overflow, which also causes a crash.
