5686,Member function and member variable pointers don't work well with shared_ptr,patvarilly@…,Peter Dimov,"The current implementation of shared_ptr doesn't overload operator->*, so member function and member variable pointers don't play nicely with shared_ptrs.  I would imagine that this is trivial to fix given the existing operator-> implementation.  Here's an example of what doesn't work but should:

{{{
#!cpp
class A
{
public: int memberA;
}

...
int A::*memberVariablePtr = &A::memberA;
shared_ptr<A> ASharedPtr( ... );

// The following two pieces of code should be functionally identical

// 1) Doesn't compile.  Error in g++: ""base operand of -> is not a pointer""
//      It took me a while to figure out what g++ was complaining about
int val = ASharedPtr->*memberVariablePtr;   

// 2) Compiles and works just fine
int val = ASharedPtr.get()->*memberVariablePtr;
}}}

Note: I tried this with version 1.45.0, but looked up the documentation of shared_ptr in 1.46.1 to make sure that this hasn't already been addressed.",Bugs,closed,To Be Determined,smart_ptr,Boost 1.45.0,Problem,wontfix,shared_ptr pointer-to-member,
