Memory debugger for mixed-mode C++ applications

I have to maintain a large C++ mixed-mode application (VC++ 2005, CLR-support: /clr:oldsyntax). I suspect the program has a number of memory leaks but it's hard to find them manually. For native C++ applications we use Purify (and Valgrind on Linux).

Unfortunately Purify does not support mixed mode assemblies. Anybody here knows a decent memory debugger wit开发者_如何学JAVAh support for mixed mode assemblies?

Take a look at AQTime. I've used it and it's pretty decent. They also provide a free trial version that's unhindered (last I checked).
