[boost] [regex]Including regex.hpp causes error in an skeleton win32 project of VS.net2003 with MFC support

Hello, I have done a test, on WinXP + VS.net 2003, with regex lib as follows , A created a new 'Win32 Console Project', I selected MFC and pre-compiled header support. Leave other settings default. Then I created a skeleton project that can compile. Then I added #include <boost/regex.hpp> in the main cpp file. When I then compiled the program in debug mode, I got a "error C2665" at regex_raw_buffer.hpp(177) - “operator new. When I compiled it in release mode, it's Ok. Anybody know how about this phenomenom? Thanks Max
