Description David Balažic 2001-03-26 10:57:43 UTC 
I compiled screen-3.9.8-3.srpm with the -DDEBUG option,
by changing the line in screen.spec :

<make CFLAGS="$RPM_OPT_FLAGS -D_GNU_SOURCE"
>make CFLAGS="$RPM_OPT_FLAGS -DDEBUG -D_GNU_SOURCE"

Then I added the line "debug on" in /home/root/.screenrc
and run screen. It showed the splash page and after I
pressed return it crashed. Last line in /tmp/debug/SCREEN.19784 was :

ASSERT(new >=0 && new <= 9) failed file display.c line 1836

I attach all three files from /tmp/debug and the used spec file.

The contents of ~root/.screenrc are :

bell_msg "bla"
debug on

Comment 5 Crutcher Dunnavant 2001-06-26 20:21:24 UTC 
this doesnt seem to happen in 3.9.9
Comment 6 David Balažic 2001-07-26 10:24:03 UTC 
screen-3.9.9-1 recompiled with -DDEBUG

Crashes at the same point if /etc/screenrc contains a single line :
debug off

( actually you must use /usr/etc/screenrc , due to a packaging bug,
see bug #49535 )
Comment 7 David Balažic 2001-07-26 10:30:20 UTC 
I forgot to mention that this time no assertion failure is reported, it just 
dies.
Comment 8 Phil Copeland 2002-08-12 18:06:40 UTC 
Umm this is an unsupported change.
I don't see this behaviour in 3.9.11-8

Try rawhide (ftp://ftp.redhat.com/pub/redhat/linux/rawhide/SRPMS/SRPMS)
