COleDataSource clipboard method is crashing in Widows XP after closing the application

Our project(MFC Active X project) is developed using VC++ 2010.
We are using COleDataSource methods to copy data to clipboard. We are using the below code snippet to copy data on clipboard

COleDataSource* pSource = new COleDataSource();
HGLOBAL hText = ::GlobalAlloc(GMEM_SHARE, iTextSize);
LPSTR pText = (LPSTR) :: GlobalLock(hText);
ASSERT(pText);
strcpy(pText, strClipboardText);
::GlobalUnlock(hText);
pSource->CacheGlobalData(CF_TEXT, hText);
pSource->Flushclipboard();
The above code snippet is in ActiveX control. When we close the application it is crashing in XP. The same code snippet is working in Window 7.

The call stack is showing as below

NOTE: The same scenario is working when application build in debug mode(mfc100d.dll)
