4! Tests fix for PR25018 in which an ICE resulted from using a
5! variable in a parameter initialization expression. In the course
6! of developing the fix, various other constraints and limitations
7! were tested.

18! This is OK because it is a restricted expression.

22    real(8) :: y (0:,:)
23    integer :: i
24    real :: z(2, 2)

26! However, this gives a warning because it is an initialization expression.
27    integer :: l1 = len (ch1)     ! { dg-error "Assumed or deferred character length variable" }

29! These are warnings because they are gfortran extensions.

31    integer :: m4(2) = shape (z)

33! This does not depend on non-constant properties.
