一个调试问题：Invalid Address specified to RtlSizeHeap，麻烦看看！

[NistCK]

下面这段代码, 调试的时候发现Add方法在连续调用几次后便出现: HEAP[MRServer.exe]: Invalid Address specified to RtlSizeHeap( 130000, 146678 ).
不知问题出在哪了? 麻烦高手看看。谢谢！

代码如下:

#include <vector>

public:
CProperty(){
m_bstrPropName = BSTR("");
m_bstrPropValue = BSTR("");

BSTR m_bstrPropValue;
};
//-----------------------------------------------------------------

//-----------------------------------------------------------------
// DataBuffer.H
//-----------------------------------------------------------------
typedef std::vector<CProperty, std::allocator<CProperty> > PROPERTYVECTOR;

class CDataBuffer {
public:
BSTR GetData();
BSTR GetKey();
boolean SetKey(BSTR bstrKey);
boolean SetData(BSTR bstrData);
CDataBuffer(){}
virtual ~CDataBuffer(){}
private:
CComBSTR m_bstrKey;
CComBSTR m_bstrData;
PROPERTYVECTOR m_Prop;
};

// DataBuffer.CPP
boolean CDataBuffer::SetData(BSTR bstrData){
m_bstrData.Attach(bstrData);
return true;
}

boolean CDataBuffer::SetKey(BSTR bstrKey){
m_bstrKey.Attach(bstrKey);
retur true;
}

BSTR CDataBuffer::GetKey(){
return m_bstrKey.Copy();
}

BSTR CDataBuffer::GetData(){
return m_bstrData.Copy();
}

};

// Center.CPP

DATAVECTOR gData;

STDMETHODIMP CCenter::Add(BSTR bstrKey, BSTR bstrInfo,long* pResult){

return S_FALSE;
}

return S_FALSE;
}
}
CDataBuffer oDB;
oDB.SetKey(bstrKey);
oDB.SetData(bstrInfo);
gData.push_back(oDB);
*pResult = gData.size();

return S_OK;
}

调试进去看哪行有问题

看看 call stack.
