Comment (by nbruin):
OK, two independent patches. Either prevents the segfault. I may just have
removed the symptom, but not the cause.
If I'm correctly understanding the problem,
[attachment:trac_13447-consolidated_refcount.patch] should be the
preferred solution. However, my unfamiliarity with (lib)singular's
intricacies might have caused an oversight somewhere. I think my
interpretation is consistent with the use in
`sage.lib.singular.function.call_function`, which is my main source of
inspiration.
If people agree, we can clean out the cruft remaining from the refcounting
method implemented locally.
