That's been fixed for quite a while,
with the latest versions just manipulating text
for simple integers like this, and so can work
for any length strings.

thanks,
Pádraig.

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

Oh, it should have been fixed from release 8.20 (2012-10-23)

Yes. That range triggers the fast string manipulation code here.
It's very surprising it doesn't there.

I see that seq is on OS X:
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/seq.1.html
So please ensure you're not using the native seq, and rather gseq

If still an issue, you'd need to debug it further there
as I've not got access to OS X here.

thanks,
Pádraig.

You are correct, my apologies! I was still using the default seq, not gseq
installed by brew!

How embarrassing. Thanks for the help!
