32F429IDISCOVERY board hard fault/default handler

I'm trying to implement a GOCR algorithm to 32F429IDISCOVERY board. The GOCR itself works very well on PC but on the discovery board I'm still having some issues that makes it unstable and unusable. Sometimes the algorithm works fine, everything goes well and the result is great but sometimes the processor gets stuck in hard fault/default handler. I cannot tell what is the reason of the crash and what am I supposed to do but I believe that stack/heap got overflowed. The crash always happens on normal instructions that were done few times before. Below I attached an image that shows the state of the processor before and after the crash:

Thanks for your help of comments...
