Off by one fix

[James William Pye]

I committed a fix for an off by one error that I believe was causing this[1].
Basically, it would crash on create function due to using more memory than what
it had allocated(about a byte). This went unnoticed on FreeBSD, but screamed
frequently on glibc/linux systems.

If anyone had any random trouble with the backend(notably on CREATE FUNCTION),
please try the current HEAD for a likely fix. 

Adrian, I believe you submitted this[1], can you confirm that this is fixed now?
