Memory leak detection under Windows for GNU C/C++

What memory leak detection tools are available for use with open source C/C++ on Windows?

From stackoverflow

• WinDbg is always a good choice for any program open or closed.

• DebugDiags

• LeakDiag. Quite hard to find nowadays, but available here. You might also like to get LDGrapher, available in the same place.

• I've been using VLD (Visual Leak Detector) for some times, it works nicely for good code, for more complex code; it's not perfect.

  Chris Morley : Newer version at author's home page: http://dmoulding.googlepages.com/vld

  Rob Kam : From the documentation: It is designed specifically for use with Visual C++, and it depends on heap debugging functions found only in Microsoft's C runtime library.

• The mem package is an effective and straightforward tool to detect memory buffer overflows, underflows, leaks, double-deletion, and dangling references.
