[Boost-users] [boost.function] member function with default values for parameters

Folks,

What is wrong with the code below:

class SomeClass
{
public:
   int doSomething(int i=0)
   {
      return ++i;
   }
};

boost::function2<int, SomeClass*, int> func = &SomeClass::doSomething;
SomeClass sc;
std::cout << func(&sc, 1);

Currently I'm having following error:

An object or reference of type "boost::function2<int,SomeClass
*,int,std::allocat
or<boost::function_base> >" cannot be initialized with an rvalue of type
"int
(SomeClass::*)(int)".

If I remove default value for parameter i  - everything compiles. Complier:
VisualAge 7.0

Thanks
