[Bug c++/15469] New: Unable to compile valid code including transform() algorithm

["relf at os2 dot ru" <gcc-bugzilla at gcc dot gnu dot org>]

While compiling the code below, gcc 3.3.3 reports the error:

bug2.cpp:21: error: no matching function for call to `transform(
   std::_Rb_tree_iterator<std::pair<const int, int>, std::pair<const int,
   int>&, std::pair<const int, int>*>, std::_Rb_tree_iterator<std::pair<const
   int, int>, std::pair<const int, int>&, std::pair<const int, int>*>,
   __gnu_cxx::__normal_iterator<int*, std::vector<int, std::allocator<int> > >,
   <unknown type>)'

The code looks correct, not much different from the C++ Standard section 18.6.2
examples.
secondof() function by itself works fine - i've included a line into the code to
demonstrate that.

==============================

#include <iostream>
#include <map>
#include <vector>
#include <algorithm>
using namespace std;

template <class cl1, class cl2>
const cl2& secondof(const pair<cl1,cl2>& p) {
    return p.second;
}

int main() {
    map<int,int> M;
    M[1] = 10;
    M[4] = 50;

    cout << "secondof() works as expected: " << secondof(*M.begin()) << endl;

    vector<int> V(M.size());

    transform(M.begin(),M.end(),V.begin(),secondof);
}
