!==================initialization_1.f90======================
! { dg-do compile }
! Tests fix for PR25018 in which an ICE resulted from using a
! variable in a parameter initialization expression. In the course
! of developing the fix, various other constraints and limitations
! were tested.

module const
! The next line is the original error
real(8), parameter :: g = - sqrt(2._8) * Gf ! { dg-error "not been declared or is a variable" }
contains
subroutine foo(ch1, x, y)
character(*) :: ch1
! This is OK because it is a restricted expression.
character(len(ch1)) :: ch2
real(8) :: x (1:2, *)
real(8) :: y (0:,:)
integer :: i
real :: z(2, 2)
! However, this gives a warning because it is an initialization expression.
integer :: l1 = len (ch1) ! { dg-error "Assumed or deferred character length variable" }
! These are warnings because they are gfortran extensions.
integer :: m3 = size (x, 1) ! { dg-error "Assumed size array" }
integer :: m4(2) = shape (z)
! This does not depend on non-constant properties.
