Comment (by ncohen):

 It is very likely that this segfault comes from the code itself. Do you
 think that this should stop us from turning it into a module ?

 What we currently ship in Sage returns wrong results, and this new version
 of the code fixes it. Though we have segfaults. Could you try to run this
 code with the old version of Sage, see if it works ?

 I could build a package with the old version of the code, if it does not
 segfault. It would still return wrong results, though.

 > Also, have you seen that I don't always have the same answer on the
 Petersen?

 Yesyes. I cannot reproduce that on my computer either, but it was
 apparently reported in #13744.
