ifort's error message is apparently based on this restriction in the F08
standard:

"C5100 (R569) A common-block-object shall not be a dummy argument, a result
variable, an allocatable variable, a derived-type object with an ultimate
component that is allocatable, a procedure pointer, an automatic object, a
variable with the BIND attribute, an unlimited polymorphic pointer, or a
coarray."

This is what really makes the original test case invalid.
