replacing new with macro conflicts with placement new
You can catch placement new with a variadic macro:
#define NEW_DEBUG(...) NEW_DEBUG2(_NORMAL_BLOCK, __FILE__, __LINE__, __VA_ARGS__ )#define new NEW_DEBUGBut the preprocessor doesn't seem to allow defining a macro both witharguments and without, and a macro without arguments is applied first,so I didn't find a way to do this with a single preprocessor pass.But it seems possible with two, if we'd run first pass with above macros and /E,then second pass with
#define NEW_DEBUG new(_NORMAL_BLOCK, __FILE__, __LINE__)#define NEW_DEBUG2(...) new(__VA_ARGS__ )
