! { 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. ! !
