GNAT is correct. The corrigendum says in 10.1.5(7.1/1):
A library unit pragma that applies to a generic unit does not apply to its
instances, unless a specific rule for the pragma specifies the contrary.
That means that a categorization pragma does not apply to instances of the
generic, only to the generic itself. (You need to be able to say that a
generic is Pure so it can be withed and instantiated in a Pure package; but
that doesn't necessaryly make it Pure - that depends on the formals).
The pragma on the instance is not "confirming"; it gives the categorization.
See AI-00041 for a full discussion.
