Or on Linux by injecting a SIGINT with strace:
strace --trace-fds 0 -e read --inject=read:signal=SIGINT:when=2 \
-E INPUTRC=/ -E HISTFILE= -E PS1='$ ' \
-E ASAN_OPTIONS="${ASAN_OPTIONS:+$ASAN_OPTONS:}detect_leaks=0" \
./bash --norc -in <<< $'\cR\e'
$ read(0, "\22", 1) = 1
(reverse-i-search)`': read(0, "\33", 1) = 1
--- SIGINT {si_signo=SIGINT, si_code=SI_KERNEL} ---
$ --- SIGINT {si_signo=SIGINT, si_code=SI_USER, si_pid=303292, si_uid=1000} ---
