What is the best free memory leak detector for a C C program and its plug-in DLLs

Question

I have a  exe and many plug-in  dll modules that the  exe loads   I have source for both   A cross-platform  with source  solution would be ideal  but the platform can be narrowed to WinXP and Visual Studio  7 1 2003 in my case    The built-in VS leak detector only gives the line where new malloc was called from  but I have a wrapper for allocations  so a full symbolic stack trace would be best   The detector would also be able to detect for a leak in both the  exe and its accompanying plug-in  dll modules

As for me I use Deleaker to locate leaks  I am pleased

My freely available memory profiler MemPro allows you to compare 2 snapshots and gives stack traces for all of the allocations

I personally use Visual Leak Detector  though it can cause large delays when large blocks are leaked  it displays the contents of the entire leaked block

If you don t want to recompile  as Visual Leak Detector requires  I would recommend WinDbg  which is both powerful and fast  though it s not as easy to use as one could desire    On the other hand  if you don t want to mess with WinDbg  you can take a look at UMDH  which is also developed by Microsoft and it s easier to learn   Take a look at these links in order to learn more about WinDbg  memory leaks and memory management in general    Memory Leak Detection Using Windbg Memory Leak Detection in MFC Common WinDbg Commands  Thematically Grouped  C C   Memory Corruption And Memory Leaks The Memory Management Reference Using LeakDiag to Debug Unmanaged Memory Leaks Heap  Pleasures and Pains

As several of my friend has posted there are many free leak detectors for C    All of that will cause overhead when running your code  approximatly 20  slower  I preffer Visual Leak Detector for Visual C   2008 2010 2012   you can download the source code from - enter link description here
