possible bug with VC++ and shared_ptr

I'm using MSVC++ v6sp5 and I have noticed that the following compiles 
without error:

--- file: test.cpp ---
#include <boost/smart_ptr.hpp>
#include <stdio.h>

void main() {
  boost::shared_ptr<int> p( new int(5) );
  p= 0;
  printf( "%x\n", p.get() );
}
----------------------

What's worse is that it prints out a non-zero number for p.get(). 
Obviously p.reset( 0 ) has the desired effect, which makes sense 
since p's constructor is marked explicit. Assignments of the form "p= 
0" appear to generate no errors, warnings or object code for all 
cases where p's operator= is templated.

Is this a confirmed bug in VC++ or have I missed something dreadfully 
obvious? Is there a workaround for shared_ptr?
