问题
I'd like to make use of Electric Fence in an MFC application. I'd like to track new/ delete, and if I can track malloc/ free that's an added bonus.
Unfortunately, MFC redefines new and delete - but using macros (DEBUG_NEW) - so I can't use the standard C++ method of redefining them. (MFC defines them to have different signatures, with source file and line numbers as additional parameters).
Is there any way to force all new/ deletes to go via my allocator, and stop MFC trying to grab these allocators?
回答1:
You can stop the MFC hooking of new by redefining DEBUG_NEW in the end of stdafx.h
#undef DEBUG_NEW
#define DEBUG_NEW new
