> On the one hand, that's true. On the other, we were only hitting this
problem on one or two platforms. So it might be a bug in some component
of Sage (like GLPK?), but it might be something out of our control
entirely.
Nothing is out of my control... ;-)
I mean we should try to find the reason. If it's outside of Sage, fine,
and we can at least document it, whether it lies in GLPK or some
OS/compiler specifics.
And the "failing" doctest, i.e. the behavior after timing out, in addition
shows (again) that something's wrong with the doctesting framework, to
also be addressed on another ticket.
> So a work-around seems like an acceptable solution right now.
I'm ok with merging this work-around at this moment.
> Have you tried setting the number of vertices higher on other machines,
to try to replicate the issue elsewhere? I just tried with 40 instead of
30 on sage.math, and it worked just fine. 50 vertices took a while, but
it finished, too.
Not yet, currently trying to track this issue (with 30 vertices) further
down.
Please cc me if anyone opens a follow-up.
