--- Comment #2 from vehre at gcc dot gnu.org --- This is no regression, because before the patch mentioned in comment #1, the construct of having allocatable components in derived types was flagged as error. Now this construct is supported for derived types at least. For class-typed coarrays looking up the token fails. This bug is similar if not a duplicate of pr77785.
