Can you reproduce the issue without using MEX or Matlab? Looking at your code, the wrap_intfunc and intfunc are relatively simple. The mex Function has quite a bit of behavior that might segfault. I am not saying your code is the culprit, but removing that much code from the debug would be helpful. Just understanding the ultimate arguments of the GSL function call would help. - Rhys >
