It's not a crash, it's a deliberate abort.

Because C-g input to a GUI frame is delivered to Emacs as SIGIO, while
to a TTY frame it is delivered as SIGINT. The processing is very
different, and AFAIU cannot be the same, because these two signals
have very different attributes on Posix systems.
See my other message, which described what happens here in more
detail.
