SIGINT cannot cause a crash in -nw sessions.  Emacs programs the
terminal to produce SIGINT when you type C-g, and when SIGINT is
delivered, Emacs converts it into a QUIT -- just like you expect when
you type C-g in Emacs.

The only way to cause Emacs to abort via SIGINT in -nw sessions is to
press C-g several times quickly enough while Emacs is busy -- this
activates the so-called "emergency exit" feature, whereby Emacs will
abort after asking you whether you really meant that.
