internal compiler error: cc1 got fatal signal 11

[Peter Schmid]

When I compile this program, it is from the gcc.testsuite, the compiler
crashes  with a segmentation fault.
It seems that a null pointer p is dereferenced in line 464 of tree.c in
function restore_tree_status. 
Sorry I don`t know, what is the correct way to fix this.

cat 921215-1.c

main()

  void p(void ((*f) (void ())))
    {
      void r()
	{
	  foo ();
	}

      f(r);
~    }

  void q(void ((*f)()))
    {
      f();
    }

  p(q);
#endif
  exit(0);
}

foo(){}
