--- Comment #2 from Volker Reichelt <reichelt at gcc dot gnu.org> ---
While the original testcase was invald, here's a valid one that crashes
in the same place:

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

template<typename T> void bar(T)
{
  (A().foo)();
}
====================================

bug.cc: In function 'void bar(T)':
