! { dg-do compile }
! One of the tests of the patch for PR30068.
! Taken from the fortran 2003 standard C11.2.
!
! The interface is invalid although it is unambiguous because the
! standard explicitly does not require recursion into the formal
! arguments of procedures that themselves are interface arguments.
