Although trying that version, which does compile, results in all zero values being printed, as if the subroutine was not executed. I.e. copy-in, but no copy-out.  That is the case for multiple compilers.

The code is not conforming, even without the INTENT.  The text from paragraph 19 of, which you cited in the first message of this thread, says that the variable is not definable.  The text that follows the phrase "the dummy argument is not definable" does not make the dummy argument definable.
