Here is the smallest code I could come up with to reproduce the

I was able to reproduce the warning with an even smaller snippet of
code:
#include <vector>
#include <functional>
#include <boost/function.hpp>
int main()
{
std::vector< std::size_t sizes;
std::vector< unsigned data;
boost::function< bool (unsigned, unsigned) fn = std::greater<
unsigned >();
fn( data.front(), 10 );
}
The warning goes away if I comment out the line "std::vector<
std::size_t sizes;". This behavior baffles me. Any insight would
again be appreciated.
Thanks,
Matt
