[GNU sed] bug report

[Khanh-Dang]

Hi,

I have discovered a bug in GNU sed :
here is a shell session :

$ echo "':" | sed "s/\(.*\)\'://"
Segmentation fault
$ sed --version
GNU sed version 4.0.7
Copyright (C) 2003 Free Software Foundation, Inc.
[...]
$

I'm am working on a GNU/Linux system and sed was compiled with gcc 3.2.3 
on a Gentoo distribution.
The bug is also reproductible with GNU sed version 4.05, on a RedHat 9 
system.

There is no bug when typing the same command but without the backslash 
before the char ':

$ echo "':" | sed "s/\(.*\)'://"

$


Please apologize for my bad english.
