! { dg-do compile }
! Tests the fix for the interface bit of PR29975, in which the
! interfaces bl_copy were rejected as ambiguous, even though
! they import different specific interfaces. In this testcase,
! it is verified that ambiguous specific interfaces are caught.
!
! Contributed by Joost VandeVondele <jv244@cam.ac.uk> and
! simplified by Tobias Burnus <burnus@gcc.gnu.org>
