# *bash* 4.0 vs. typing `C-c` (*SIGINT*)
Will show `-bash: echo: write error: (ipc/mig) wrong reply message ID` unter
certain conditions.
After having noticed that this error doesn't occur if starting *bash* with
`--norc`, I isolated it to the following command in `.bashrc`:
case $TERM in
xterm* | rxvt*)
PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}:${PWD}\007"';;
esac
... and indeed:
tschwinge@flubber:~ $ echo "$TERM" -- "$PROMPT_COMMAND"
xterm -- echo -ne "\033]0;${USER}@${HOSTNAME}:${PWD}\007"
tschwinge@flubber:~ $ ^C
-bash: echo: write error: (ipc/mig) wrong reply message ID
tschwinge@flubber:~ $ PROMPT_COMMAND=
tschwinge@flubber:~ $ ^C
tschwinge@flubber:~ $
bash-4.0$ PROMPT_COMMAND='echo >&2 -n foo\ '
foo bash-4.0$ ^C
bash-4.0$ PROMPT_COMMAND='echo >&1 -n foo\ '
foo bash-4.0$ ^C
bash: echo: write error: (ipc/mig) wrong reply message ID
bash-4.0$ PROMPT_COMMAND='/bin/echo >&1 -n foo\ '
foo bash-4.0$ ^C
bash: start_pipeline: pgrp pipe: (ipc/mig) wrong reply message ID
So, there's something different with stdout in / after the SIGINT handler.
