Hmm, I get garbage answers for the second and later rows, rather than
a core dump.

I think the guilty party is the pfree() in dist_pb. Given this set of
data close_pb will return its input Point pointer, so the net result is
dist_pb tries to pfree the supplied constant. A bad move :-(.
I am strongly inclined to rip out *all* the pfrees of someone else's
result in geo_ops.c, not only that one. Given the current handling of
memory management they are a waste of cycles and code space, and after
seeing this example I am not inclined to trust them not to be pfreeing
something they shouldn't.
