Most curious.
I can repro your symptoms.  However, the following combinations do work:

   cat r1s.gz | gunzip > r1s
   zcat r1s.gz > r1s

It seems only directly re-directing stdin fails.

Hmm...there's something rather strange about this specific .gz file of
yours.  I'll have to analyse it a little more to determine what's going
on.  On a guess, I'd say there's a control sequence in it that's tickling
the I/O handler in some interesting way.

How, exactly, (if I may ask), did you create this file?
It looks like random noise to me.
