Please describe exactly what actions triggered the bug and the precise symptoms of the bug:
In 34.3.1.1 Emacs Lisp Reference , Note that `\' also has special meaning in the read syntax of Lisp
strings (*note String Type::), and must be quoted with `\'. For example, the regular _expression_ that matches the `\' character is `\\'. To write a Lisp string that contains the characters `\\',
Lisp syntax requires you to quote each `\' with another `\'. Therefore, the read syntax for a regular _expression_ matching `\' is `"\\\\"'. The last sentence , it should be " .... matching `\\' is `"\\\\"' ".
If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'. If you would like to further debug the crash, please read the file
/usr/share/emacs/23.0.96/etc/DEBUG for instructions.
