This is a bug report for perl from dyuret@ku.edu.tr,
generated with the help of perlbug 1.34 running under perl v5.8.3.


-----------------------------------------------------------------
[Please enter your report here]

\pL does not behave as it should in some regular expressions.
Example program:

#!/usr/bin/perl -w
my $foo = 'H';
my $bar = ($foo =~ /^(\w\.)*\w$/);
my $baz = ($foo =~ /^(\pL\.)*\pL$/);
print "[$bar] [$baz]\n";

Example output:
[1] []

You would expect to get the same result in both cases.
