1.7.9: zsh, "unexpected end of file"

1.7.9: zsh, "unexpected end of file"

[Thomas Hafner]

Hello,

could zsh be repaired such that it behaves successfully like bash?
Here goes the problem description.

1. In shell /usr/bin/zsh-4.3.12.exe:
  gunzip < r1s.gz > r1s
  - Expected: unpack to r1s
  - Observed: command fails with output "gzip: stdin: unexpected end of
    file"
2. However this works:
  gunzip r1s.gz
3. If I repeat 1. with bash rather than zsh, it works.

The file r1s.gz can be get there http://tinyurl.com/bs7kefh .

Regards
  Thomas Hafner

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.
