Description of problem:
If you have an expect script that produces large amounts of output the output 'sticks' and repeats at some point.  This seems to be the same behavior described in bug
#147276 but I observe it in any terminal.  

[jennings@weimar ~]$ expect 
expect1.1> spawn perl
spawn perl
expect1.2> interact
print $i++,"\n" while (1)

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. see above

Actual Results:  The output gets to about 10000 and starts to repeat.

Expected Results:  The output should count upwards until you stop it

I see this is an old bug report.  I just recently took ownership of the expect
package, so I'm trying to get caught up.

Two things:

1)  I can't do anything for FC3 as that's now unsupported.

2)  On rawhide (what will become FC5), I ran your test above and the problem
doesn't appear for me.  I let it run to 509003 and killed it.  Rawhide has

If you're running FC5 Test 2 or rawhide, can you confirm the behavior is fixed?

Comment 2 Guy Jennings 2006-01-31 17:18:24 UTC
Yes, it was fixed in a later version
