Have you tried the suggested fix from the email thread Paul cited? Sounds to me like the most likely cause of the problem, assuming it comes from inside OMPI.
Have you looked at the backtrace to see if it is indeed inside OMPI vs your code?

I don't know if it is because of my code or not, but I run the program for small matrices sizes and the program completes until the end without error while for large inputs it will hang or give that sigv.
