I wouldn't think so.  pnt->str == NULL means that the table has an
explicit entry that intentionally maps to NULL.  Either the caller
meant for that to happen, or it's a caller coding error.

At most, this function could assert pnt->str != NULL, but I don't
think this is the same condition as in the other look-up function.
