Here's another way to crash Tk:

trace variable OUCH r { kill }
proc kill {args} { destroy .b }
checkbutton .b
.b configure -variable OUCH

==> segmentation fault

Low priority, as this is an unlikely scenario.

    fixed in 8.4.5 and 8.5a0 with a check against DELETED flag
    after configuration. Just returns an empty error - could be
    improved.
