   1 ! { dg-do compile }
   2 ! This tests the patch for PR29098, in which the presence of the default
   3 ! initializer would cause allocate to fail because the latter uses
   4 ! the interface assignment.  This, in its turn was failing because
   5 ! no expressions were found for the other components; and a FAILURE
   6 ! was returned from resolve_structure_cons.
