Recipe:

Launch emacs -Q.

C-x C-f emacs-bug-038.el
M-x eval-buffer

Wait for approximately one minute.

The contents of emacs-bug-038.el are:

------
(run-with-timer 0 .01 (lambda () (message (make-string 1 0))))

(while t
  (let ((f (make-frame)))
    (sit-for .1)
    (delete-frame f)))
------

The repository is unmodified Emacs HEAD; while the CFLAGS contain an extra
option to dump gimple trees, I believe that should have no influence on the
produced code. I have attached a full gdb log.

I have been unable to reproduce this bug with emacs -Q --load
emacs-bug-038.el.

Please let me know if I can provide any further information or do anything
else to help fix this bug.
