Steve, I will throw this one back at you. I asked earlier, but never got a
response:
What happens if the dummy (with the IGNORE attribute) is declared as
INTEGER(4), and things are performed inside that the standard defines only
for 4-byte integers (e.g., some bit packing operation). Then, the routine is
called with a REAL(8) array? What if the array is of a derived type of size 1
byte?
What specifically will Intel Fortran do? Compile and give results that make no
sense? If so, the standard must have *specific* restrictions on what the
actual is allowed to be, and what it means. Only illegal cases can be left
without a meaning.
What does Cray do?
If the routine is written in C and has a void* argument, I understand how it
works. But I do not understand how it works if "everything is written in
Fortran".
Best,
Aleks
