Comment (by ncohen):
Well, this patch does not contain a line of Cython so it is quite unlikely
that it could produce a segfault by itself. The problem most probably
comes from subgraph_search, which occasionnally segfaults (it happens to
me sometimes when I interrupt it during a computation).
This being said I was not able to reproduce it on my computer.
