--text follows this line--
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing
list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
In 34.3.1.3 Backslash Constructs in Regular Expressions of Emacs Lisp
Reference ,
If a particular grouping construct in the regular expression was
never matched--for instance, if it appears inside of an
alternative that wasn't used, or inside of a repetition that
repeated zero times--then the corresponding `\DIGIT' construct
never matches anything. To use an artificial example,,
`\(foo\(b*\)\|lose\)\2' cannot match `lose': the second
alternative inside the larger group matches it, but then `\2' is
undefined and can't match anything. But it can match `foobb',
because the first alternative matches `foob' and `\2' matches
`b'.
After "To use an artificial example" , there are two commas .
PS. why can I not send bug in emacs ?
it says :Sending...failed with exit value 1
Thanks
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.
