Hi
I used boost::intrusive_ptr in a function, say foo(), like this:

    boost::intrusive_ptr<BranchFeedback> theFeedback ( new BranchFeedback() );
    std::vector< std::vector< BPredState > >           theFetchState;
    ....
    theFeedback->theBPState = &theFetchState[anIndex][!anOne];

The difinition of BranchFeedback and BPredState are:

  struct BranchFeedback : boost::counted_base {
    ...
    boost::intrusive_ptr<BPredState> theBPState;
   };
  struct BPredState : boost::counted_base {
    ...
    uint32_t theGShare;
    uint32_t theSerial;
  };

The problem is when foo() reaches the end (I mean '}'), I get segmentation fault which points to 
    ~intrusive_ptr()
    {
        if(p_ != 0) intrusive_ptr_release(p_);
    }

I thought I used the intrusive_ptr in a correct way. Is there any consideration that I missed?
Thanks,
