That makes a certain amount of sense as This is Debian Sparc64 which as I understand it has the kernel compiled in 64-bit mode but not most of userland. I bet if I compile Postgres in 64-bit mode it'll turn up as an alignment issue in userland before it even reaches the kernel. Or maybe not, maybe it's just that __put_user is stricter about alignment than really necessary. -- greg -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
