| Dale, who are "they"?  Anyway, this is an *implementation* bug, not a

No, it's a design bug, since actually using the construction was
forbidden in FORTRAN II, the compiler wasn't required to handle it in
any decent way.

If the compiler claims to be FORTRAN *IV*, then it's an implementation
bug.
