[graph-tool] all_circuits crashes on 2.22

Hi all, I'm running 2.22 on Ubuntu 16.04. Iterating over all_circuits() results in a segmentation fault. e.g., cycles = gt.all_circuits(G) for c in cycles: ... I also tried iterating over it by cycles.next() to see which cycle causes the crash. Turns out it crashes sporadically at different iterations. Sometimes on the first, sometimes on the seventh, etc. This happens for all combinations of python 2.7 and python 3.6 under WSL 16.04 or pure 16.04 Ubuntu. My cursory search didn't get me anywhere. Is this a bug or an error on my part? Your help is appreciated, -- Sent from: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/
