Description Tim Waugh 2003-02-13 18:06:16 UTC
Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install kernel that warns.
2. Run screen.

Comment 1 Lon Hohberger 2003-02-14 18:24:44 UTC
The place screen sets SIGCHLD to SIG_IGN is only in the exit path; I can't get
the above warning to actually occur.

Could someone else then test 3.9.13-4?   Dist-8.0.1-HEAD

Comment 2 Ingo Molnar 2003-02-14 19:35:31 UTC
The message triggers with 3.9.13-4 as well. It does not trigger for every
startup of screen - i got 1 message out of 3 tries. I'm running screen as
non-root, over ssh. (perhaps this is a factor as well.)

Comment 3 Lon Hohberger 2003-02-18 14:00:42 UTC
Indeed, it is.  Thanks for the additional information. Fix coming ASAP.

Comment 4 Lon Hohberger 2003-02-18 16:43:27 UTC
The bug seen was in actually in utempter.  However, I have closed all obvious
windows where screen could exhibit the buggy behavior.  (Exit path, and during
the re-attach process).

3.9.13-5... will be in as soon as it finishes building.

Comment 5 Lon Hohberger 2003-02-18 19:16:51 UTC
I tested this package a few (50 or so) more times with the latest build of
utempter - everything seems fine. Closing.
