Comment (by simonpj):

 Yes, this is bug all right.  The Report says

       It is an error to use module M in an export list unless M is the
 module bearing the export list, or M is imported by at least one import
 declaration (qualified or unqualified).

 Fixing this involves the same data structures as those used for reporting
 unused imports, so it would be sensible to fix this bug at the same time
 as #1074
