Erk.
Seems to be a font-lock related transpose-regions problem.
emacs -Q
Type "abcd" in scratch
M-: (transpose-regions 1 2 3 4)
Debugger entered--Lisp error: (args-out-of-range 0 0)
get-text-property(0 font-lock-multiline)
font-lock-extend-jit-lock-region-after-change(0 0 0)
run-hook-with-args(font-lock-extend-jit-lock-region-after-change 0 0 0)
jit-lock-after-change(0 0 0)
transpose-regions(1 2 3 4)
eval((transpose-regions 1 2 3 4))
eval-expression((transpose-regions 1 2 3 4) nil)
call-interactively(eval-expression)
If you repeat the experiment and disable font-lock before calling
transpose-regions, Emacs segfaults.
