Thanks Steve for the confirmation.  Your "always a bug" statement is of course correct, though I'd imagine it takes on a much lower priority with vendors if it is associated with invalid code.

In fact it works with gfortran 8.0.0 too!  (What doesn't work with gfortran is if subroutine SUB is in a separate source file -- you get an internal compiler error.  The developer wants to dismiss the issue as being due to invalid code.)

Is that code valid, or am I out to lunch on this one?

 The specification expression is legal for the reasons you state. But even if it weren't, an internal compiler error is ALWAYS a compiler bug, even in the presence of invalid code. It is true that ncells needs to be assigned a value before the function is called for the program to be valid, but that's beside the point.
