! 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.
