! { dg-do run }
! This tests the "virtual fix" for PR19561, where pointers to derived
! types were not generating correct code. This testcase is based on
! the original PR example. This example not only tests the
! original problem but throughly tests derived types in modules,
! module interfaces and compound derived types.
