reading all the comments in the gcc bug report, this is because x86 targets the x87 fpu by default which is where the bug is -- it's a hardware problem. x86_64 targets sse which has stricter standards for rounding. most x86 processors support sse -- is there a reason why we don't target sse? merlin -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
