Description rfowler 2000-04-13 22:22:45 EDT
In a KDE Konsole terminal window, if you type "clear" at the command line
prompt to clear the screen, a core file is created and the screen is not
cleared.  (Fortunately, Konsole keeps running.)  This bug appeared in 6.2;
it was not present in 6.1 or 6.0.
Comment 1 Tim Waugh 2000-04-14 09:40:59 EDT
I can't reproduce this.  Was it an installation or an upgrade, and if an
installation which installation path did you choose?
Comment 2 Anonymous 2000-04-14 22:41:59 EDT
I have the same issue. I installed with a 6.2 KDE workstation install.
I didn't format the /usr partition, however.

I see the bug both in the kconsole and in any xterms that I spawn.
Comment 3 Anonymous 2000-04-15 20:40:59 EDT
I don't have this problem... clear works just fine. I upgraded my RH 6.0
directly to RH 6.2.
Comment 4 Bernhard Rosenkraenzer 2000-05-05 09:55:59 EDT
Can't reproduce it...
Please send me the output of "strace clear".
Comment 5 forun 2000-06-16 13:08:12 EDT
I get a similar behavior in aterm's.  Here is the output of strace:

Comment 6 Bernhard Rosenkraenzer 2000-08-08 08:30:38 EDT
Still can't reproduce it anywhere. Please attach the core dump file.
Comment 7 Bernhard Rosenkraenzer 2000-08-31 05:53:44 EDT
We've tried this on more than 200 machines now and can't reproduce it anywhere.
If this still happens for you, make sure that
- you are not using a broken termcap file. Re-Install the Red Hat Linux termcap
and ncurses RPMs,
  and delete any .termcap or .terminfo files/directories you have in your home
directory.
- make sure you're using the Red Hat Linux packages. You can use rpm -V to
verify their
  integrity.
