Ah, that might do it, it's not a placement new, it's a call to ::operator new. There's no way to suppress macro expansion on a non-function macro either is there?
AFAIK, no, but nobody can be sure of any pp statement without talking to Paul Mensonides, first :) You could detect whether "new" remains the same after an attempted expansion or not, though.
Quite depressing, I know. As you'll see, this causes problems to themselves too:

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."

Doesn't work?: #include <boost/regex.hpp> #ifdef _DEBUG #define new DEBUG_NEW #endif Many headers seem to escape into 'stdafx.h'. It looks best to include regex.hpp in 'stdafx.h'. -- Shunsuke Sogame
