! { dg-do compile }
! One of the tests of the patch for PR30068.
! Taken from comp.lang.fortran 3rd December 2006.
!
! Although the generic procedure is not referenced and it would
! normally be permissible for it to be ambiguous, the USE, ONLY
! statement is effectively a reference and is invalid.
