Bug #39569 for Algorithm-LCSS: Bug in Algorithm::LCSS - uninitialized value warnings

Dear Dr Freeman, I have a very simple proposed patch for a small bug in the the CPAN module Algorithm::LCSS, which apparently you wrote. If you try to run LCSS on two sequences that don't have a common substring, then as it stands the module will print the following error message to STDERR: Use of uninitialized value in array element at /usr/lib/perl5/site_perl/5.8.8/Algorithm/LCSS.pm line 70. This is a little bit messy and I was hoping to get rid of these error messages. This can be achieved very easily by inserting a new line just before the existing return statement at the end of the sub: return unless defined($index); return $css->[$index]; } This will provide the same functionality but without the error message. If you could implement this patch, that would be much appreciated. Thanks. Regards, ------------------------- Jeremy Krieg Senior Software Engineer YourAmigo Ltd.
