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 with support for mixed mode assemblies?
