I expected that the compiler reject it. 
But Comeau compiler also accepted this code.
gcc 2.95.3 don't generate code that causes segmentation fault.(LINK error)
another test case:
following invalid code causes ICE.

template <class T>
void foo()
{
  T bar = 0;
  bar();
}

int main()
{ 
  foo<int ()>();
  return 0;
}
