Start the IDE (doesn't matter if it's a saved image or (require'cocoa)).

Invoke m-x grep, e.g. M-x Grep<Enter>Exchange Point

In the grep window, double click on first found line

Click on title bar of grep window to select it again

Click on close box of grep window

Crashes into kernel debugger dereferencing 0 (perhaps something is trying to display the grep window after it already started deallocating some of its data structures...)

FWIW, I'm running 10.4.10 on a PPC G4.

Once a process is allowed to run to exhaustion, it never again responds to process-interrupt:

(let ((p (make-process "Test")))

  ;; Let it run through once
  (process-preset p #'(lambda () nil))
  (process-enable p)
  (process-wait "exhaust" #'(lambda () (process-exhausted-p p)))

  ;; Now revive it and try to interrupt it
  (process-preset p #'(lambda () (sleep 10)))
  (process-reset p)
  (process-enable p)
  (sleep 1)
  (let ((test :never))
    (process-interrupt p #'(lambda () (setq test :interrupt)))
    (process-wait "exhaust" #'(lambda () (process-exhausted-p p)))
    test))

In a new buffer, enter

(foo "bar

then place the insertion point after the quotes and press, e.g., c-m-f. IDE will wedge and has to be killed.

I think the problem is that generally, hemlock code isn't prepared to navigate inside strings (valid-spot is nil), but much of the time it doesn't actually check for it so in some cases it just goes into infinite loops.
