I can reproduce it in 4.1.2(1)-release and 4.0.23(1)-release on x86_64
GNU/Linux. I didn't try on bash 3.2.

An amd64-specific bug, then? (The Linux box I tested on earlier is i386,
and the HP-UX box is PA-RISC 2.0.)
I guess the bug is somewhere in glibc and specific for 32 bit systems.
(2^63) is same as (2^63/-1) on 32bit system (tested on ppc32).
