bug#30687: 25.3; Crash when pressing CTRL + g multiple times

[Kristian Rumberg]

Sometimes  when I press CTRL + g multiple times inside Emacs, it
crashes. I have seen this bug in multiple versions of Emacs so it's
not a recent bug. For the first time I received a stacktrace when it
exited

emacs -nw getsubs.rs
Auto-save? (y or n) y
Auto-save done
Abort (and dump core)? (y or n) y
Fatal error 6: Abort trap
