I see.  The explicit template parameter needs to be updated too.

#include <boost/bind.hpp>
#include <boost/bind/protect.hpp>
using boost::bind;

//#include <boost/lambda/bind.hpp>
//using boost::lambda;

template<class Handler_t>void Test2(Handler_t Handler)
{
}

template<class Handler_t>void Test1Impl(Handler_t Handler)
{
    bind(&Test2<Handler_t>, Handler)();
}

template<class Handler_t>void Test1(Handler_t Handler)
{
    Test1Impl(boost::protect(Handler));
}

void TestFunc(int i)
{
}

int main()
{
    Test1(bind(TestFunc,0));
}
