! { dg-do run }
! Test the fix for pr22146, where and elemental subroutine with
! array actual arguments would cause an ICE in gfc_conv_function_call.
! The module is the original test case and the rest is a basic
! functional test of the scalarization of the function call.
!
! Contributed by Erik Edelmann <erik.edelmann@iki.fi>
! and Paul Thomas <pault@gcc.gnu.org>
