overlapcoefficient causes segment fault if either parameter is an empty string #6

If either parameter passed to overlapcoefficient is an empty string rather than null, a segment fault is raised. I can repeat this with the extension installed on Amazon Linux 2012-09 running Postgresql 9.2. I compiled the pg_similarity code from c12cc00.

Here's an example:

values(overlapcoefficient('hello',''))
