Indeed it does, thanks. (I actually combined your suggestion to use
Emacs's multi-tty capability with Michael Snyder's to attach the emacs
process to gdb: I did the latter from within the Emacs client. This had
the advantage over running gdb directly from the shell that I could copy
and paste the backtrace from the shell buffer to my followup buffer in
Gnus.)
(Before reading your post I had tried sort of the inverse strategy: I
started emacs under gdb from a virtual console, switched to X, invoked
emacsclient -c from an X terminal and induced the abort. However, when
I switched back to the virtual console the gdb process was dead. In
hindsight this was obviously a flawed strategy, but I'm still learning
how to use the multi-tty capability. When will the doc be ready? ;-) )
