Description Volker Reichelt 2009-06-07 20:35:31 UTC 
The following invalid code snippet triggers an ICE since at least GCC 2.95.3:

=================================
struct A
{
  typedef void (&F)();
  template<int> operator F();
};

void foo()
{
  A()();
}
=================================

bug.cc: In function 'void foo()':
bug.cc:9:7: internal compiler error: in add_template_candidate_real, at cp/call.c:2477
Please submit a full bug report, [etc.]
