Comment (by cdavid):

 This has nothing to do with scipy version, I think.

 The problem being a stack overflow, there are only two solutions:
  - increase your stack size (on my system, I have a default stack size of
 8192, setting it to 32768 was enough to avoid the segfault: ulimit -s
  - change the implementation to avoid deep recursion

 The later would mean rewriting the algorithm, I guess.
