How to detect memory leak of ipp?

I am using Intel Ipp and found out that the memory leak caused by memory allocating function ippiMalloc cannot be detected by neither crtdbg.h nor Visual Leak Detector. I wonder is there any tool available to detect memory lead caused by ipp's function like ippiMalloc in windows. Thinks :)

Hu,

In Windows, performance monitor will allow you to detect memory leaks. Check the following official documentation: https://msdn.microsoft.com/en-us/library/windows/hardware/ff560134(v=vs.85).aspx

BTW, if you find a memory leak related to Intel Integrated Performance Primitives, I do believe the best forum to post the details about your research so that it is investigated by Intel engineers is the Intel Integrated Performance Primitives forum: https://software.intel.com/en-us/forums/intel-integrated-performance-primitives

If possible, make sure you can provide all the details of the code that is generating the memory leak.

BTW, any additional

BTW, any additional information you have about this topic, I suggest you to put it in the forum I suggested in my previous post. It makes more sense and you will have help from the most appropriate Intel engineers.

>>...allocating function ippiMalloc cannot be detected by neither crtdbg.h nor Visual Leak Detector... This is because _mm_malloc is used internally by IPP, and also many other Intel libraries. MS VS based Memory Leaks Detection is based on using malloc_dbg C-Runtime function instead of malloc C-Runtime function for Debug configurations.
