--- Comment #13 from kargl at gcc dot gnu.org ---
I intend to close this PR after updating the information
about Cray pointers and an assumed-sized array.  The
Fortran clearly states


8.5.8.5 Assumed-size array
An assumed-size array is a dummy argument array whose size
is assumed from that of its effective argument, ...

An assumed-sized simply cannot appear in the specification
portion of a module. The text in gfortran.info will be


    The pointer is an integer that is intended to hold
    a memory address. The pointee may be an array or scalar.
    If an assumed-size array is permitted within the scoping
    unit, a pointee can be an assumed-size array. That is, the
    last dimension may be left unspecified by using a * in place
    of a value. A pointee cannot be an assumed shape array. No
    space is allocated for the pointee.

 The pointee may have its type declared before or after the pointer
 statement, and its array specification (if any) may be declared
