(Re-submitting/formatting to get under the 40K message size limit)
The coredump @565 is due to tp being NULL. Since it just got past the assertion @563, the problem has to be down in cs_add().
563 assert(tp);
564 cs_add(&t->tables, tp, TR_OLD);
565 tp->p = t;
I've dug down into cs_add(), but it isn't obvious to me where tp is getting set to NULL. Since it looks like you have a fairly straightforward test case, I would submit a bug report.
