bug#10649: 23.4; Regexp char classes not working


From: Raffaele Ricciardi
Subject: bug#10649: 23.4; Regexp char classes not working

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the address@hidden mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

--- Beginning of description ---
- start emacs -Q
- evaluate this forms:
(string-match "[:xdigit:]" "0")
(string-match "[:xdigit:]" "a")
(string-match "[:alnum:]" "5")
They should return non-nil, but they return nil instead.

Found not working also on Emacs 23.3b and 24.0.92.1.

Cheers.

--- End of description ---

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'.
For information about debugging Emacs, please read the file
