! { 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.
! This test checks that the main uses for elemental subroutines work
! correctly; namely, as module procedures and as procedures called
! from elemental functions. The compiler would ICE on the former with
! the first version of the patch.
