! { dg-do run }
! { dg-options "-std=legacy" }
!
! This tests the fix for PR24276, which originated from the Loren P. Meissner example,
! Array_List. The PR concerns dummy argument aliassing of components of arrays of derived
! types as arrays of the type of the component. gfortran would compile and run this
! example but the stride used did not match the actual argument. This test case exercises
! a procedure call (to foo2, below) that is identical to Array_List's.
