bug#276: 23.0.60; crash after C-x 5 1


From: Eric Hanchrow
Subject: bug#276: 23.0.60; crash after C-x 5 1
Date: Sun, 18 May 2008 21:47:46 -0700
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/23.0.60 (gnu/linux)

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I had started emacs in console mode, created one or two X frames with
M-x make-frame-on-display, and then did C-x 5 1 from the console frame.

SIGINT is used by the debugger.
Are you sure you want to change it? (y or n) [answered Y; input not from 
terminal]
DISPLAY = localhost:10.0
