L.S. After playing around with grep I found a bug when using the -P flag for Perl regular expression.
See this minimal example: [EMAIL PROTECTED]:~> echo "x" | grep -P "x[\s+]" Segmentation fault while [EMAIL PROTECTED]:~> echo "x" | grep -E "x[\s+]" does work (it return nothing as expected). My version: [EMAIL PROTECTED]:~> grep -V grep (GNU grep) 2.5.1 Copyright 1988, 1992-1999, 2000, 2001 Free Software Foundation, Inc. This is free software; see the source for copying conditions.
