The first test case of comment 0 seems to be still unfixed (accepts-invalid -
expected error not printed).


The test case from comment 6 gives an ICE (segfault) in
gfc_conv_procedure_call's check for
          f = (fsym != NULL)
            && !(fsym->attr.pointer || fsym->attr.allocatable)
            && fsym->as->type != AS_ASSUMED_SHAPE;
(guess: "fsym->as" is NULL)


Comment 7 fails - but that's seems to be fixed by the patch of comment 12 (cf.
also below).
