Hmm, so the problem is in that second loop. The trick is to pick some reasonably non-ugly code change that makes the problem go away. The first thing I'd try is to get rid of the overly cute optimization int rightnodeno = leftnodeno + 1; and make it just read int rightnodeno = rightchild(nodeno); If that doesn't work, we might try refactoring the code enough to get rid of the goto, but that looks a little bit tedious. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
