I pushed up a new test case in https://github.com/llvm/llvm-project/commit/a244194f73788de6dfd6d753ff09be3625613f9f that shows it (and set the C status page back to Partial in case this takes a while to address), but `case` and `default` labels should be accepted the same as any other label at the end of a compound statement.

Hi! Thanks for this information! How did you find out that we should accept labels at end of statement in **C**, but not in **C++**? That is not obvious for me unfortunately. If C supports it, why would C++ not support it?
