Hello, Steven

Your test case is failed in my environment. I use boost 1.36.0

then I replaced my boost with 1.39.0 and found it works!

What's the difference between them?

This was a bug up to 1.38. The problem was that the expression used in result_of<> passed the arguments by value which fails with abstract base classes. -Thorsten
