If I start out with a standard white background and font colors, the crash
occurs when I attempt to evaluate the region in question.  But if those
commands are in my .emacs, I don't get an immediate crash.  But I do get it
if I set the point at the beginning of the region and then rapidly use C-n
to move the cursor down the lines of code, including the commented lines,
which now have various colors.

This is repeatable on two different iMacs in two different locations.

From my earlier message:

"GNU Emacs 23.0.60.1 (i386-apple-darwin9.4.0, *Step 9.0)
 of 2008-08-05 on
phi-qp617070u2s.Princeton.EDU<http://phi-qp617070u2s.princeton.edu/>
"
Using an Apple intel iMac running OS 10.5.4

Running for a couple of hours, then when I tried to a region containing the
following expressions, emacs hung.
gdb output follows the expressions whose evaluation appears to have caused
the problem.  I just tried the same thing again and the problem is
repeatable.

Here's a simpler case.
Start emacs with: nextstep/Emacs.app/Contents/MacOS/Emacs -Q
Taking the file as the region do "eval region".  I get a crash.
On the other hand, "eval buffer" does not crash.
