bug#5811: 23.1.94; Emacs Nextstep port crashes after graphical yes-or-no


From: Chong Yidong
Subject: bug#5811: 23.1.94; Emacs Nextstep port crashes after graphical yes-or-no-p
Date: Thu, 01 Apr 2010 11:31:47 -0400
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/23.1.94 (gnu/linux)

Could you take a look at this bug report?  Thanks.

David, it would help if you compile Emacs without optimizations.  That
makes the stack trace easier to read.
