+! { 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>
