template<int> struct A
{
  template<typename T> operator T();
};

void foo()
{
  A<0>().operator auto();
}
==========================================

bug.cc: In function 'void foo()':
bug.cc:8: internal compiler error: tree check: expected function_decl, have
template_decl in build_over_call, at cp/call.c:5123
Please submit a full bug report, [etc.]

------- Comment #3 from jakub at gcc dot gnu dot org  2008-11-28 08:20 -------
Moving the error ("invalid use of %<auto%> in conversion operator");
diagnostics to cp_parser_conversion_type_id (or caller), although it fixes
this testcase, doesn't work too well, because then for auto9.C some of these
errors are reported twice (during tentative parsing and then again when
parsing for the second time).  So it should be probably diagnosed later, but
I'm unsure where.  Jason?
