Hello Loïc, I didn't get a segfault when I run neither 'echo -foo | grep --color=auto -vw foo' nor 'echo -foo | grep -vw foo'. When I run 'echo -foo bar | grep --color=auto -w foo -foo bar', I get: -foo bar with "foo" coloured red. $ dpkg -l grep libc6 | grep ^ii ii grep 2.5.3~dfsg-1 GNU grep, egrep and fgrep ii libc6 2.6.1-1+b1 GNU C Library: Shared libraries $ locale LANG=en_AU LC_CTYPE="en_AU" LC_NUMERIC="en_AU" LC_TIME="en_AU" LC_COLLATE="en_AU" LC_MONETARY="en_AU" LC_MESSAGES="en_AU" LC_PAPER="en_AU" LC_NAME="en_AU" LC_ADDRESS="en_AU" LC_TELEPHONE="en_AU" LC_MEASUREMENT="en_AU" LC_IDENTIFICATION="en_AU" LC_ALL= Best Regards, Aníbal Monsalve Salazar -- http://v7w.com/anibal
