/* Testcase to exercise the code path in bug 13961.

   Compiled from:

   class foo
   {
    public:
     int bar;
   };

   foo baz;

   int
   main ()
   {
     return 0;
   }

   And then manually edited to insert the necessary DW_AT_specification
   entries to trigger the desired code path.
   There's no real need to make this architecture-specific, so it has been
   further hand-edited to support that.
