This is a bug report for perl from jorda@edpsciences.org,
generated with the help of perlbug 1.33 running under perl v5.6.1.

UNDER LINUX, perl 5.6 (see config below)
Running the following program leads to a 'Segmentation fault' :


#! /usr/bin/perl -w


$toto = 'Hello';
$toto =~ /\w/; # this line provokes the problem!


$name = 'A B';
if ($name =~ /(\p{IsUpper}) (\p{IsUpper})/){
    print "It's good! : $1 $2  \n";
} else {
    print "It's not good...\n";
}
# end of the program


UNDER SunOS,with perl 5.8

This leads to "It's not good...",
instead of the expected "It's good! A B". if I suppress 
$toto =~ /\w/; 
I get the right result.
