Hey Geoff, thanks for your advice. I try to run the matleap.cpp from Matleap by jeffsp. The compiler had problems with the libstdc++.so.6 so I relinked it to the compiler libstdc++.so.6 as it is described here. Now it crashes after running.

Hi Ma, I have faced this "Segmentation Violation Error" while compiling C/C++ code. Following are two major causes which I found while solving the issue which might help to you. 1) A pointer variable is used without defining its size 2) And in your code you are accessing a hard coded memory location which is protected or your compiler cannot access this memory location.

Hey Shrirang, thank you for your help. I don't think that it is a problem with the size, because the code ( matleap code ) has been verified on other systems. Am I right?
