[Bug c++/38228] [4.2/4.3/4.4 regression] ICE with invalid use of bound member function

[reichelt at gcc dot gnu dot org]

------- Comment #3 from reichelt at gcc dot gnu dot org  2008-12-28 23:43 -------
Simpler testcase:

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

struct B
{
  void foo();
};

A a = B().*(&B::foo);
===============================

This is invalid use of a bound non-static member function.
You have to call the function: (B().*(&B::foo))()

This has nothing to do with C++0x.
The bug is related to PR26496 which fixed a similar case long ago.
The code ICEs since GCC 3.4.0 and was wrongly accepted before.
