Created attachment 731717 [details] My .screenrc Description of problem: Occasionally screen will segfault. It appears to happen when alternate screen support is on ("altscreen on") and an application that is using the alternate screen does "something" (ie. exits). Version-Release number of selected component (if applicable): [0 zerodogg@firefly ~]$ rpm -qv screen screen-4.1.0-0.14.20120314git3c2946.fc18.x86_64 How reproducible: I've been unable to reliably reproduce it. It has happened several times, on two different boxes - both running F18. Additional info: The last time it crashed I had a gdb attached to the screen process, so I was able to get a backtrace: Program received signal SIGSEGV, Segmentation fault. 0x00007f158483c3cc in ChangeWindowSize () (gdb) bt #0 0x00007f158483c3cc in ChangeWindowSize () #1 0x00007f158483cbd4 in LeaveAltScreen () #2 0x00007f1584832818 in DoCSI () #3 0x00007f1584835138 in WriteString () #4 0x00007f1584844d0b in win_readev_fn () #5 0x00007f158487131a in sched () #6 0x00007f158482986a in main () I also have a coredump, but I am a bit wary of uploading that publicly since I had programs with personal information (ie. mutt, which was the one that triggered the segfault this time). I'll be happy to share it privately, however.
