Re: Bug in bash 4.4-beta: suspending and restarting "man" program

[Keith Thompson]

I have some more information on this.  In the latest test,

the problem occurs when I run bash under rxvt, but not when I run it under xterm.

Using strace, I've found a difference in a call to rt_sigaction().  It calls

rt_sigaction(SIGTSTP, {SIG_DFL, ...})

under xterm (which works correctly), but

rt_sigaction(SIGTSTP, {SIG_IGN, ...})

under rxvt (where it doesn't).

I've been playing with rxvt and urxvt lately, which might explain why I've seen the problem. Apparently there's some

difference between xterm and rxvt in the way they invoke the shell.

What's the output of trap?
