Correct, the function will be called with 12. You can ensure this with
this small program:

#include <iostream>
#include <boost/bind.hpp>
#include <boost/function.hpp>

void resolveHandler(int param)
{
  std::cout << param << std::endl;
}

boost::function<void (int)> functionPtr;
int tempInt = 12;

int main()
{
  functionPtr = boost::bind(&resolveHandler, tempInt);
  functionPtr(67);
}
