I'm running bash 4.4-beta, built from bash-4.4-beta.tar.gz, on two different x86_64 systems, one running Debian 6.0.10 and another running Linux Mint 17.3.
On both systems, if I run "man rm" (for example) I can read the "rm(1)" man page using "less" (my $MANPAGER is set to "less -s -r"). If I then type Ctrl-Z, the "man" and "pager" processes are suspended and the screen is restored its previous state. On the Debian system, I don't get a new shell prompt (this is the bug). The terminal continues to accept and echo input, but it's otherwise stuck. Ctrl-C and Ctrl-Z are echoed as "^C" and "^Z", but are otherwise ignored. I can recover by killing the "man" process from another window. On the Linux Mint system, this problem does not occur. Typing Ctrl-Z gives me a new shell prompt, and the "man rm" process shows up in the "jobs" listing. The problem does not occur on Debian 6 using /bin/bash (version 4.1.5). I don't see the problem when I invoke "less" or "vi" directly. I've seen the problem when I'm in an editor (vim) invoked from "git commit". So apparently it has something to do with a full-screen program invoked by some other program. Let me know if I can provide more information (Debian 6 is fairly old, so you might not have a running copy). -- Keith Thompson <keith.s.thomp...@gmail.com>
