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?
