Yes, the MS nasty macro definition is the source of problem.
The workaround is commenting out the macro as follows:

//#ifdef _DEBUG
//#define new DEBUG_NEW
//#endif

As indicated in the MS web page, the drawbak of this solution is,
as quoted from the page:

"NOTE: This method has the disadvantage of not using features in 
MFC that help you track memory allocations and leaks."
