bigint binding problems in sqlite3

I created a @Column that was type "bigint" and when inserting very large numbers, they were getting capped in SQLite3 at 2147483647.

I switched Doctrine/DBAL/Types/BigIntType.php, line 46 from:

return \PDO::PARAM_INT;

to:

return \PDO::PARAM_STR;

and now it is storing the full numbers. I am unsure, however, whether this is the right change or will affect other database layers. Any thoughts?
