Setting the following trap makes an interactive bash (any version) exit on
issuing SIGINT:
trap 'trap "true" INT; kill -s INT $$; trap - INT; kill -s INT $$' INT
# ^^^^^^^^^^^^^^^ eat signal ^^^^^^^^^^ unset trap
After setting that trap, pressing Ctrl+C, or otherwise causing SIGINT to be
sent, causes an interactive bash to exit.
Thanks for the report.
