Re: crash

This code is looking more and more wrong to me. This patch has moved _more_ code that calls Lisp into the critical portion of redisplay. This is right under a comment that says we should be getting rid of such code. Why does the gutter update code call out to Lisp? This seems exactly backward from the way the rest of redisplay works, which is to let Lisp make state changes and then have redisplay compute the difference between the current display and what the new display should look like. If you call out to Lisp inside redisplay then more state changes can be introduced, which might mean that redisplay never completes or never gets the display right.
