the point is actually that it shouldn't pass :-) 
both ifc and nag reject the code (line 20 should read: end subroutine sub1)

No, this is an error from NAG f95. Normally a very good reference when it comes
to the standard, but I'm not sure why this wouldn't be allowed.

Well, the compiler can't easily check for this (e.g. subroutines in different
files) and if the data type don't have the same size it is really likely to be
an error, even if not pendantic. It is up to the programmer to get this right.
See also comment #3. I'm fairly sure such errors are the reasons for a number of
the (machine dependent) failures observed.
