error C2833: 'operator DEBUG_NEW' is not a recognized operator or type
When compiling an application (in which a header file has just been changed) the Microsoft Visual C++ compiler generates the compiler error:
... \include\crtdbg.h (536) : error C2833: 'operator DEBUG_NEW' is not a recognized operator or type
followed by in excess of 20 errors.
Normally the compiler error C2833 means that the specified symbol is not recognised and this indicates a simple programming error.
This specific error, in ‘crtdbg.h’ involving ‘
DEBUG_NEW’, is a compiler bug. This bug has been observed in Visual
Studio 5 and Visual Studio 6 (up to and including service pack 5).
These remedies deal with the compiler bug only.
- Try recompiling. This sometimes cures the problem.
- If recompiling does not cure the problem then ‘clean’ the affected project and rebuild. This has always been observed to cure the problem.
- Anders Musikka has contributed the following tip: It is not necessary to do a full clean of the project and rebuild. You can just delete the xxx.pch file in the debug/release directory and recompile the failed .cpp file(s).
Whilst it is in no way conclusive, this bug may be related to the project pre-compiler header settings. I have noticed that it only seems to affect projects where the precompiled headers is set to ‘automatic use of precompiled headers’.
