> Guys, getting a segfault in sort using large input set. The behavior
> changed to always use the number of processors available in parallel by
> default. The following commands (taken from cracklib installation which
> is where I first saw the error) work to successfully reproduce the error
> (in a chroot environment):
>
> zcat cracklib-words-20080507.gz | sort -u
>
> The following, however, works fine on my system:
>
> zcat cracklib-words-20080507.gz | sort -u --parallel=1
>
> Can somebody else on a mult-core CPU, on 32-bit, confirm before I
> troubleshoot further?
