bug#70122: 29.3.50; transpose-regions can crash Emacs

From: Braun Gábor
Subject: bug#70122: 29.3.50; transpose-regions can crash Emacs
Date: Mon, 01 Apr 2024 12:02:35 +0200 
Hi,

I have the following file:

File ~/.emacs.d/trans-regions-bug.el:

(with-temp-buffer
  (insert (propertize "a" 'face 'font-lock-variable-name-face))
  (insert ":\n")
  (insert (propertize "b" 'face 'font-lock-variable-name-face))
  (insert ": \x2113\x2080\n")
  (insert (propertize "v" 'face 'font-lock-variable-name-face))
  (insert ": scaling\n")
  ;; Move last line to the beginning
  (transpose-regions 1 1 10 21))

End of file ~/.emacs.d/trans-regions-bug.el:


After building Emacs as described in the INSTALL file, the following
command crashes Emacs:

  src/emacs -Q --batch -l ~/.emacs.d/trans-regions-bug.el

The following appears:

Fatal error 11: Segmentation fault


See below for debugging information.

Please find attached a patch to transpose-regions
with added tests.  (The patch intends to fix typos:
makes sure lengths in bytes and characters are not confused.
One case (likely for optimization only) has been removed,
seemed too much trouble to get it right.)
