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

This REGEX doesn't work equal on Linux & Win32:

$data = q`
HTML1
<% CODE1 %>
HTML2
<% CODE2 %>
HTML3
`;

  while( $data =~ /(.*?)<%(.*?)%>\n?/gs ) {
    print "<<< $1 >>>\n" ;
    print "<<< $2 >>>\n" ;
  }

  if ( $data =~ /.*<%.*?%>\n?(.*?)$/s ) {
    print "<<< $1 >>>\n" ;
  }


Take a look in this node at PerlMonks: http://www.perlmonks.com/index.pl?node_id=238273
I let a full text of the bug. And I put a test script that send the test output to a server and save them.
I will publish all the reports in a reply of this node too. For now the bug exist on Linux and OpenBSD, on Perl-5.6.1 & Perl 
5.8.0.
