The problem is that 'functionPointer' is not defined within 'helperFunc2'. Which BaseClass instance contains the function pointer that you want to call on 'classPointer'? If it is classPointer itself, then that line should read:
(classPointer->*classPointer->functionPointer)( 7 );

Great, this works :-)

Also, I should say that I'd be surprised if virtual functions didn't eliminate most of your need for function pointers.
