Stack Smashing here is actually caused due to a protection mechanism used by gcc to detect buffer overflow errors. For example in the following snippet: The compiler, (in this case gcc) adds protection variables (called canaries) which have known values.

It is a guard against a stack overflow, yes. Python (or rather, the CPython implementation) doesn’t optimize tail recursion, and unbridled recursion causes stack overflows. You can check the recursion limit with sys.getrecursionlimit: and change the recursion limit with sys.setrecursionlimit: but doing so is dangerous — the standard limit is a little conservative, but Python … Read more
I think your code is trying to “divide by zero” or “divide by NaN”. If you are aware of that and don’t want it to bother you, then you can try: For more details see: http://docs.scipy.org/doc/numpy/reference/generated/numpy.seterr.html
