SQLSTATE[HY000]: General error: 50240 [Vertica][Support] (50240) Invalid buffer position.

I have a very simple PHP query that return an error: 50240 Invalid buffer position.

This is the code I am using to test:

$query = "select * from category where name = :nome";       
$sth = $this->_lnk->prepare($query);       
$category = 'Hardcore';       
$sth->bindParam(':nome', $category);       
$sth->execute();


- This is the trace from vertica_odbc.log:

- This is the error:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 50240 [Vertica][Support] (50240) Invalid buffer position. (SQLExecute[50240] at /builddir/build/BUILD/php-5.4.20/ext/pdo_odbc/odbc_stmt.c:254)' in /admin_vertica_report.class.php on line 39


The unique solution we found was not use the prepared statement.

Any thoughts?
