Description:
------------
Running a SQLite 2 query that starts with a hash (#) causes a
segmentation fault. I don't believe hashes are correct comment syntax in
SQLite so the query is quite certainly invalid and should cause an
error.
Test script:
---------------
<?php
$db = sqlite_open(':memory:');
sqlite_query('#', $db);
Actual result:
--------------
