Hi Padraig,

You say "quite a while".

This issue was found in: coreutils-8.23_1

Installed on OS X using brew.

Pulling the current source I can see there have been several releases since
then, but a git diff / log doesn't seem to produce any relevant changes,
i.e.:

git diff v8.23.. -- src/seq.c

Are you *sure* that this range in particular doesn't reproduce in the
latest?

I'm happy to investigate further myself, but I need to get set up to build
coreutils first.

Thanks

Thad
