Package: screen Version: 4.8.0-6 Severity: important Dear Maintainer,
I freshly installed screen. I don't think I have any pre-existing configuration on this machine. I also don't think I have any weird system config. Please consider the following shell session: -- >8 -- nabijaczleweli@tarta:~/uwu$ screen [screen caught signal 11. (core dumped)] nabijaczleweli@tarta:~/uwu$ -- >8 -- (Also, I have ulimit -c set to 0, so not only is there no coredump, there can't be one). The same happens when I run screen -r, which I decided to do seeing as /run/screen/S-nabijaczleweli/ had some sockets in it: -- >8 -- srwx------ 1 nabijaczleweli users 0 Jan 7 02:38 100395.pts-0.tarta srwx------ 1 nabijaczleweli users 0 Jan 7 02:40 184228.pts-0.tarta srwx------ 1 nabijaczleweli users 0 Jan 7 02:40 184368.pts-0.tarta srwx------ 1 nabijaczleweli users 0 Jan 7 02:40 187419.pts-0.tarta srwx------ 1 nabijaczleweli users 0 Jan 7 02:40 188181.pts-0.tarta srwx------ 1 nabijaczleweli users 0 Jan 7 02:41 190201.pts-0.tarta srwx------ 1 nabijaczleweli users 0 Jan 7 02:44 308064.pts-0.tarta srwx------ 1 nabijaczleweli users 0 Jan 7 02:38 97741.pts-0.tarta -- >8 -- Attaching a strace -f screen (which indicates that it catches SIGABRT, not SIGSEGV? wild) and the coredump (after raising ulimit -c). Please advise? Am I holding it wrong? (How wrong indeed if it ends up like this?)
