--- Begin Message --- Subject: 23.0.60; CVS Emacs.app crashes randomly Date: Fri, 12 Sep 2008 02:50:25 -0400
Emacs.app randomly crashes on me when in normal use.  I can be editing code, 
using gnus, or simply composing an email.  It's happened when I try to save a 
file, when I switch to emacs from another app, or when I hit return a couple 
times.  So it just seems to happen randomly.  It doesn't hang, it just exits 
immediately (without prompting me to save any files)

When I run it in gdb, instead of crashing instantly, it hangs.  I assume this 
is the point where the crash usually happens, but gdb is preventing it from 
quitting entirely.  Here's the message I see in gdb when it crashes:

The call to ns_free_indexed_color() in x_clear_image_1() (image.c:1625) had no business being there -- that color is not indexed, but a long RGB value derived from four_corners_best() or x_alloc_image_color() (which eventually calls ns_defined_color() with makeIndex=0). I checked in a removal as of 11/24, after closer examination prompted by yet another posting bug #1362. Hopefully this is the end of this!
