3 ! Tests the fix for PR78108 in which an error was triggered by the
4 ! generic operator being resolved more than once in submodules. This
5 ! test checks that the error is triggered when the specific procedure
6 ! really is inserted more than once in the interface.
8 ! Note that adding the extra interface to the module produces two
9 ! errors; the one below and 'Duplicate EXTERNAL attribute specified at (1)'
