Hi everyone,
I've dug around in the source code for several days now, and the issue is
not in the poset code specifically. Rather, the above problem is being
caused by this bug in UniqueRepresentation, which FinitePoset inherits from:
http://trac.sagemath.org/sage_trac/ticket/12215
No surprise. The problem with #12215 and related tickets (#715, #11521,
#12313) is that some memory corruptions in libsingular become immanent
only when the garbage collection works properly - hence, before being
able to merge #12215 stably into sage, one needs to fix some bugs in
(lib)singular, part of which seem to be upstream bugs.
Cheers,
Simon
