Subject: Child_changed with PTY


Hello,

I've been playing with pty, expect and Expecter (from Matz) but now I allwais 
get the same error (Child_changed). If I print something after a string is 
catched (by expect) it crashes there, and if not crashes in expect code. 
Could be my ruby version?

ruby 1.6.2 (2000-12-25) [i386-linux-gnu]

The script: 
--8<---------------
require 'expecter'
require 'pty'
 
exp=Expecter.new(2)
 
$lero=false
 
exp.on("dir") {
 
    $lero=true
 
}
 
PTY.spawn("ls") { |hR, hW|
 
    hR.sync=true
 
    exp.wait(hR)
 
}
 
pust "cosa" if $lero
--------------->8--

The output 
--8<---------------
[jfontan@pc3d ruby]$ ./responde2.rb
clustal.rb   dir.rb       responde2.rb   scan.rb    telnez.rb~
./expecter.rb:15:in `select': Child_changed: 16106 (RuntimeError)
        from ./expecter.rb:15:in `wait'
        from ./responde2.rb:20
        from ./responde2.rb:16:in `spawn'
        from ./responde2.rb:16
--------------->8--

Bye
