Same problem on two different iMacs

Start emacs with no .emacs file.

Trying to evaluate the following region hangs emacs.
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.

This went away for a while but is back for the latest pretest.

Hi Adrian,

Could you check if your recent changes caused this regression?

Thanks.

I'm unable to reproduce it (nor could I before).  I tried on both  
Tiger and Leopard.  The recent changes to font handling under NS  
should not have effected this, which seems related to colors.  There  
may still be remaining bugs in the NS color code that are exposed by  
unrelated things, so we'll just have to keep going through and trying  
to improve that code.

Dear Adrian,

Are you using Mac OS 10.5.7?

(I see this same problem on a MacBook Pro and two iMacs, all using OS
10.5.7.)

 Gil
