of cource, no memory leak.
 check out the source code of method 'reset'.
 there is a little trick help release the memory, which is similar with Effective STL: item 17: Use "swap trick" to trim excess capacity
  
 good luck

 Subject:  [Boost-users] share_ptr reset() question

  
 Hello,

Consider the following:

void createSharePtr( boost::shared_ptr<int> value)
{
    value.reset( new int(100));
}

main()
{
    boost::shared_ptr<int> y( new int(0));
    createSharePtr( y);
};

Question: Does the function createSharePtr() cause memory leak? 

Thanks,
Ben
