I encountered a segfault in `OmpStructureChecker` that is not related to a use cycle https://github.com/llvm/llvm-project/issues/234912. But this one is also a case where the segfault happens after `ResolveNames` has returned `false`, so it would probably also be fixed by exiting earlier if something went wrong in `ResolveNames`.
