! The problem was that the intrinsic operators
! were written to the module file as '/=' etc.
! but this format was not understood on reading.

! Test case by Toby White, stripped down by
! Dominique d'Humieres and Francois-Xavier Coudert
module foo
contains
function pop(n) result(item) ! { dg-warning "not set" }
integer :: n
character(len=merge(1, 0, n > 0)) :: item
end function pop
function push(n) result(item) ! { dg-warning "not set" }
integer :: n
character(len=merge(1, 0, n /= 0)) :: item
end function push
end module foo
program test
use foo
if(len(pop(0)) /= 0) call abort()
if(len(pop(1)) /= 1) call abort()
if(len(push(0)) /= 0) call abort()
