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?

Weird, no.

Regex is used and tested with VC8 a lot, although I admit I'm not in a position to test it with MFC. It's not as simple as adding:

#include <new>

to the top of that file is it?

John.

Hello John, Thank you for your hint. But unfortunately the error persists after I adding #include <new> before #include <boost/regex.hpp> Max
