Errors using shared_ptr<> and get_deleter in g++-4.1/4.3/4.4

I'm trying to use shared_ptr and get_deleter in a library I'm
developing, but having problems with syntax errors. Below is a
reduced version that shows the errors I'm getting when building with g+
+-4.1/4.3/4.4:

==================================================================
#include <iostream> // For I/O stream classes.
#include <string> // For string class.
#include <cstdlib> // For EXIT_SUCCESS.
#include <tr1/memory> // For shared_ptr.

// Forward declares/using's of types used in declarations below.
using namespace std;
using std::tr1::shared_ptr;
using std::tr1::get_deleter;

struct Base
{
     Base(): i(0) { cout << __PRETTY_FUNCTION__ << endl; }
     virtual ~Base() { cout << __PRETTY_FUNCTION__ << endl; }
     int i;
};

struct Derived: Base
{
     Derived(): num(0.0) { cout << __PRETTY_FUNCTION__ << endl; }
     virtual ~Derived() { cout << __PRETTY_FUNCTION__ << endl; }
     double num;
};

template <typename T>
struct NoDeleter
{
     void operator()(T *p)
     {
         return;
     }
};

template <typename T>
struct Deleter
{
     void operator()(T *p)
     {
         delete p;
     }
};

void test_get_deleter()
{
     Base localBase;
     Derived localDerived;

     shared_ptr<Base> localBaseSP(&localBase, NoDeleter());
     shared_ptr<Derived> localDerivedSP(&localDerived, NoDeleter());

     if (get_deleter<NoDeleter, Base>(localBaseSP))
         cout << typeid(*get_deleter<NoDeleter,
Base>(localBaseSP)).name() << endl;
     if (get_deleter<NoDeleter, Derived>(localDerivedSP))
         cout << typeid(*get_deleter<NoDeleter,
Derived>(localDerivedSP)).name() << endl;

     Base *allocBase = new Base;
     Derived *allocDerived = new Derived;
     Base *allocBase2 = new Derived;

     shared_ptr<Base> allocBaseSP(allocBase, Deleter());
     shared_ptr<Derived> allocDerivedSP(allocDerived, Deleter());
     shared_ptr<Base> allocBaseSP2(allocBase2, Deleter());

     if (get_deleter<Deleter, Base>(allocBaseSP))
         cout << typeid(*get_deleter<Deleter,
Base>(allocBaseSP)).name() << endl;
     if (get_deleter<Deleter, Derived>(allocDerivedSP))
         cout << typeid(*get_deleter<Deleter,
Derived>(allocDerivedSP)).name() << endl;
     if (get_deleter<Deleter, Base>(allocBaseSP2))
         cout << typeid(*get_deleter<Deleter,
Base>(allocBaseSP2)).name() << endl;
}

int main(int argc, char *argv[])
{
     test_get_deleter();

     return EXIT_SUCCESS;
}
==================================================================

I get the following errors:

Is this a compiler bug or "operator error"? I've tried putting angle
brackets on the constructors to try to get rid of the errors like the
ones on lines 62-64 (like so: shared_ptr<Base> allocBaseSP<Base,
Deleter>(allocBase, Deleter()), but then get the error:

      ../get_deleter.cpp:62: error: expected initializer before ?<?
token

which shouldn't be necessary since the compiler should be able to
deduce it (right?).

I added a "using std::tr1::get_deleter;" on line 10 which I don't
think I should need because of argument dependent lookup (right?) to
get rid of the error messages like the ones on lines 66-71 to no
avail.

If operator error, could anyone please tell me what I'm doing wrong or
should I report this as a g++ bug?

Mike
