For reference, Fortran 2008, "12.4.2.2 Explicit interface":

"A procedure other than a statement function shall have an explicit interface
if it is referenced and [...]
"(3) the procedure has a result that [...]
"(c) has a nonassumed type parameter value that is not a constant expression,"


(Side note: As it is not a constraint, a compiler is not required to diagnose
it. However, as it can detect it in this case, it should.)
