--- Comment #3 from sandra at gcc dot gnu.org ---
I've encountered problems related to this constraint in my WIP TS29113
testsuite, too.

https://gcc.gnu.org/pipermail/gcc-patches/2021-July/574115.html

This is the types/c535c-*.f90 tests.

The wording of the constraint is really confusing to me.  I've parsed it to
mean that the "it" being referred to as the subject of the requirements in =
the
second half of the sentence is the actual argument, not the dummy argument.

c535c-1 is emitting a nonsensical diagnostic on the subroutine definition
instead of meaningful diagnostics at the invalid call sites.

c535c-2 is failing to produce diagnostics.

c535c-3 and c535c-4 are dying with internal compiler errors.

Of course it is possible that my Fortran code is buggy as well as my parsin=
g of
the constraint.  :-S=
