+! { dg-do run }
+! Check the fix for PR16206, in which array sections would not work
+! in array initializers. Use of implied do loop variables for indices
+! and substrings, with and without implied do loops, were fixed at the
+! same time.
+!
+! Contributed by Paul Thomas   <pault@gcc.gnu.org>
+! based on testcase from Harald Anlauf  <anlauf@gmx.de>
