Not yet backported. The first issue (cf. comment 0) occurred with user code. It
is probably sufficient to only backport that one to only 4.6.

Now fixed (4.7/4.8).

Seems still to be the case.  "print *, present(y)" should print false for
comment 31 as "y" is an unallocated actual to an nonalloctable dummy. It shows
"T".

Still valid, cf. comment 36
