Only 2 years later, and I found a way around segmentation faults due to memory problems. It seems that my looping functions fill up memory over time and lead to segmentation faults at random stages. I now define such functions using the @fork decorator and then they don't seem to cause crashes any more (memory gets freed after each run). Just in case someone with a similar problem stumbles over this.
