Attaching GDB to it shows no signals being delivered on C-g, which (AIUI) hints at either SIGINT being blocked /or/ C-g =E2=80=9Cunbound=E2=80=9D from the signal via terminal settings. I=E2=80= =99ve copied the latter from a terminal used by a properly working Emacs instance with the stty(1) invocation below, yet I still see no signals via GDB, which leaves the signal mask as the only point of failure that I can think of. $ stty -F /dev/pts/non-working "$(stty -gF /dev/pts/working)"=20 Any suggestion on how do I debug this issue any further?
