I think the intention was to make configure complain if there's a -O > 2 in CFLAGS. OTOH, a unit test for multixact.c that exercises the code including wraparounds sounds like a desirable thing regardless of the fact that it could have caught this miscompilation earlier than 6 months into production. regards, Andreas -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
