I tried -1 and 1 on my Lubuntu and it still works fine.
Definitely weird, it begins to look like a CentOS build issue
but what is CentOS doing different to Lubuntu/Suse/OpenBSD etc?

 From memory CentOS is basically a free version of Red Hat
Enterprise Linux? I can't see why that would be significantly
different in stdin/out behaviour.

weirder and weirder
