/* This test triggers a crash when a physname for a subprogram has
   a method pointer to an anonymous struct as a parameter.  This
   situation is possible with templates and lambda expressions,
   reproduced here by the following source code:

   class a
   {
    public:
     int doit (void) { return 0; }
   };

  class crash
   {
    public:
     crash (int (a::*mp) (void)) {}

   remove the DW_AT_name attribute from the DIEs describing "class a."  */
