Let w.el consist of the following forms:
(start-process "bc1" (current-buffer) "bc")
(with-temp-buffer (start-process "bc2" (current-buffer) "bc"))
When I do "emacs -Q w.el", and press C-M-x on the first form, "bc"
(the GNU arbitrary precision calculator) is started and puts its
start-up message at the end of the buffer (you can also use any other
program that waits for further input). When I then press C-M-x on the
second form, the first process receives SIGHUP, and the message reads:
"Process bc1 hangup"
I can reproduce this with Emacs 22.2 and latest CVS on OSX. I tried to
trace it in gdb by putting a breakpoint at process_send_signal, but
couldn't reproduce it in the debugger. Otherwise it works every time.
In GNU Emacs 22.2.1 (i386-apple-darwin8.11.1)
of 2008-05-19 on mt-computer.local
configured using `configure '--prefix=/opt/local' '--without-x'

'LDFLAGS=-L/opt/local/lib' 'CPPFLAGS=-I/opt/local/include'
