Code below fails to compile w. intel C++ (10.0.026) .. I get the message:


bug.cpp(15): internal error: assertion failed at: "shared/edgcpfe/templates.c", line 5146
                _p = Pair(pObject, &Stub< T , METHOD >);
                          ^
compilation aborted for bug.cpp (code 4)


Any ideas?

//----------------------------------------------------------------------

#include <iostream>
#include <utility>

template < typename A0 >
class ZSignal
{
  typedef void (*StubCall)(void*, A0);
  typedef typename std::pair< void*, StubCall > Pair;

public:

  template < typename T, void (T::*METHOD)(A0) >
  void Register(T* pObject)
  {
    _p = Pair(pObject, &Stub< T , METHOD >);
  }

  void operator()(A0 a0) const
  {
    _p.second(_p.first, a0);
  }

private:

  template < typename T, void (T::*METHOD)(A0) >
  static void Stub(void* pObject, A0 a0)
  {
    T* p = static_cast< T* >(pObject);
    (p->*METHOD)(a0);
  }

  Pair _p;

};

class ZMyClass
{
public:
  void MyMethod(int i) { std::cout << "MyMethod got : " << i << std::endl; }
};

int main()
{
  ZSignal<int> d;
  ZMyClass myClass;

  d.Register<ZMyClass,&ZMyClass::MyMethod>(&myClass);
  d(12);

  return 0;
}

The ability to throw an internal error is sufficient justification for posting a problem report, regardless of whether you agree with the optional warning about unspecified order of evaluation.  That also would require you to be more specific about which compiler version you want to use.   If there is a fix, it would not likely be "back-ported" to 10.0.

oh well doesn't matter - i found the solution:

 by replacing the line:

 _p = Pair(pObject, &Stub< T , METHOD >);

with two lines:

    StubCall c = &Stub<T,METHOD>;
    _p = Pair(pObject, c);


Cheers..
