--- Comment #26 from janus at gcc dot gnu.org ---
AFAICS r243609 fixes all the various example codes posted here.

Apart from one exception: Comment 9 is rejected with these errors:

c9.f90:28:13:

     procedure :: write_formatted
             1
Error: Argument ‘this’ of ‘write_formatted’ with PASS(this) at (1) must be of
the derived-type ‘non_abstract_child2’
c9.f90:36:13:

     procedure :: write_formatted
             1
Error: Argument ‘this’ of ‘write_formatted’ with PASS(this) at (1) must be of
the derived-type ‘non_abstract_child3’


However, those already appear with version 6.2, and I hope they are correct.
Can anyone confirm this suspicion?

If yes, this PR can be closed ...
