Hide Forgot
After upgrading to the latest Raw Hide (RH6.0 worked fine, I think a Rawhide like 6-10 days back did too), irc coredumps right after being run when used with 'screen'. screen-3.9.4-2 ircii-4.4-7 glibc-2.1.2-5 rawhide-release-19990824-1
Works for me on a clean install; screen-3.9.4-2, ircii-4.4-7, glibc-2.1.2-7. Do you have anything odd in your ircii configuration?
It seems to work if I set my TERM to e.g. vt102, but if TERM=xterm, there will be a core dump.
Works OK here, in the console, xterm, & gnome-terminal. What does `rpm -V termcap` say - do you have a modified termcap?
--- rpm -V termcap --- S.5...GT c /etc/termcap --- --- rpm -q termcap --- termcap-9.12.6-15 --- --- ls -la /etc/termcap --- -rw-r--r-- 1 root adm 548317 Jan 28 1999 /etc/termcap --- Originally, this was a Redhat 5.2 box but I upgraded it to Rawhide. That might have left something behind. I haven't edited the termcap file, and it didn't help after re-installing termcap RPM either -- rpm -Uvh didn't seem to replace the old termcap. I did 'rpm -e --nodeps termcap' and installed it again. Now rpm -V reports nothing and the file looks like this: --- ls -la /etc/termcap --- -rw-r--r-- 1 root root 434898 Mar 29 19:08 /etc/termcap --- However, it still dumps the core. Here's a part of strace if it's of any help.. ------- strace irc -- ioctl(0, TIOCGWINSZ, {ws_row=28, ws_col=112, ws_xpixel=0, ws_ypixel=0}) = 0 open("/dev/tty", O_RDWR) = 3 ioctl(3, TCGETS, {B38400 opost isig icanon echo ...}) = 0 ioctl(3, SNDCTL_TMR_STOP, {B38400 opost isig -icanon -echo ...}) = 0 --- SIGSEGV (Segmentation fault) --- +++ killed by SIGSEGV +++ -------------------
Aha. You're running the rawhide libtermcap, correct? It's horribly horribly broken. Don't use it - it might even open up security holes. Downgrade to the 6.0 errata version, or wait for libtermcap-2.0.8-17, which will be in next Raw Hide release.
Libtermcap was indeed causing this. Thanks for the diagnosis!
