Well, I cannot see how the code you POSTED (you may have introduced a problem
when reducing the code, it is quite common) could be valid according the
Fortran standard. However I think the constraints that the actual and dummy
must match are put under a "shall", i.e. the burden is on the user and the
compiler may or may not detect the problem (put the call and the subroutine in
two different files instead of in a CONTAINS unit and the compiler has no way
to check that the actual and dummy argument match: a very common mistake when
using libraries).
CCed Steven G. Kargl for additional opinion.
