Demonstration of Ctrl-Z bug, bash 4.4-beta
Raw
README.md

This gist contains strace output for bash 4.4-beta on Debian 6.0.10. It demonstrates a problem with the handling of Ctrl-Z (SIGTSTP).

For some unknown reason, the behavior differs depending on whether I use xterm (where it works correctly) or rxvt (where it doesn't).

The commands I used are:

xterm -e strace -o xterm_bash.strace /usr/local/bin/bash --norc

and

rxvt -e strace -o rxvt_bash.strace /usr/local/bin/bash --norc

In both cases, I simply typed exit at the bash prompt.

/usr/local/bin/bash is version 4.4-beta, built from bash-4.4-beta.tar.gz.

xterm is version 261; rxvt is v2.6.4.

The (presumably) relevant difference is:

Under xterm (xterm_bash.strace line 77):

rt_sigaction(SIGTSTP, {SIG_DFL, [], SA_RESTORER, 0x7f26cb09bf50}, {SIG_DFL, [], SA_RESTORER, 0x7f26cb09bf50}, 8) = 0

Under rxvt (rxvt_bash.strace, line 77):

rt_sigaction(SIGTSTP, {SIG_IGN, [], SA_RESTORER, 0x7fe4ab4fff50}, {SIG_DFL, [], SA_RESTORER, 0x7fe4ab4fff50}, 8) = 0

The same problem does not occur using /bin/bash, which is version 4.1.5.
