The SIGALRM is a timer for displaying the busy cursor. The SEGV is
what causes the core dump. This is clearly in show_busy_cursor, but
dbx is not co-operating by telling me where in that function the error
occurred (does anyone know how to force ddd/dbx to believe that it is
in the correct source file? I'd use gdb, but it is not installed on
the machine, and I don't have root access).

I wonder whether the fact that we are in the middle of popping up a
menu here affects this?
