Obviously, at that point Emacs was inflooping again and C-c was ignored. Then I sent a SIGSTOP signal to emacs, which interrupted the process and was able to obtain the contents of *Messages* from gdb. >> nor C-z on the Emacs window (as DEBUG suggests.)

After executing `c', gdb showed the signal handler. Same when repeated. > What happens if you kill the GDB process, and then attach another GDB > to Emacs? Sorry, the Emacs session is gone now. Next time I'll try to not use C-g and attach gdb right away.
