Mixing scalars and arrays is invalid. But as written, the same ICE occurs if one has only arrays or only scalars (which I intended but didn't post). And do I believe the program(s) is (are) valid in that case. > I doubt that it is possible to catch the rank mismatch Well, the compiler does warn that the named common blocks have a different size.
