Re: Crash with edebug of turn-on-font-lock-if-enabled

[Richard M. Stallman]

    1. emacs -Q&
    2. M-x global-font-lock-mode
    3. in scratch buffer eval: (minibuffer-electric-default-mode 1)
    4. C-x C-f <lisp-dir>/font-core.el
    5. search defun turn-on-font-lock-if-enabled
    6. instrument this function for edebug (C-u C-M-x)
    7. load a file .e.g. ~/x.sh (with a few continues in edebug)
    8. try to kill this buffer, i.e. C-x C-k

Can you use a debugger to step thru Fkill_buffer
and its subroutines, and see why it crashes?
