I'm surprised that Emacs does that, but perhaps I'm missing something.
Here's the code that I stumbled across (as a result of a SEGV). I haven't checked to see if there are other examples. From terminal.c:
/* Deletes the bootstrap terminal device. Called through delete_terminal_hook. */ static void delete_initial_terminal (struct terminal *terminal) { if (terminal != initial_terminal) abort (); delete_terminal (terminal); initial_terminal = NULL; }
