! 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.
