I wouldn't use “robust” here. Just look at the errors types and the examples (below the table). Yes, there are some features that Clang doesn't implement at the moment or never will (GCC has some really bizarre extensions and is sometimes less strict), but there is also a great amount caused by bad code. I can't come up with a better alternative, though.
