Package: emacs
Version: 1:29.1+1-5~bpo12+1
Severity: important
X-Debbugs-Cc: braung...@gmail.com
The crash originally appeared while editing a YAML file in yaml mode,
and I've lost some unsaved changes (that's why I chose severity above normal).
Below is a small example to reproduce the bug:
File 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))
Run emacs with the following command, it crashes immediately:
emacs -Q --batch -l ./trans-regions-bug.el
Here is a backtrace with the above command run inside gdb
(with common unrelated messages remoced):
