I'm keen to find a neat solution for this too. We compile for multiple platforms, so on the non-windows side of things we can use --wrap happily. We just have to create the replacement functions and it all works without any errors or hacks.

On the windows side of things, we override the malloc calls, but then use /FORCE:MULTIPLE to deal with the linker errors. It works, the memory functions are called and everything is tracked, but it feels like a hack.

From MSDN:

A file created with this option may not run as expected. The linker will not link incrementally when the /FORCE option is specified.

Not only does it feel like a hack, it kills edit and continue in the process.

The /FORCE:MULTIPLE option might fix your problems, but I'm not suggesting it as a cure, I'm still trying to find that.
