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

How embarrassing. Thanks for the help!

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.
