Description:
------------
When fetching BINARY, VARBINARY or LONGVARBINARY data from the
data source with the (default) binary mode ODBC_BINMODE_RETURN,
the returned strings may not be properly zero-terminated, what may
cause issues later.


Test script:
---------------
<?php
$conn = odbc_connect($dsn, $user, $pass);

odbc_exec($conn, "CREATE TABLE test (id INT, whatever VARBINARY(50))");
odbc_exec($conn, "INSERT INTO test VALUES (1, CONVERT(VARBINARY(50), 'whatever'))");

$res = odbc_exec($conn, "SELECT * FROM test");
odbc_binmode($res, ODBC_BINMODE_RETURN);
odbc_fetch_row($res);
var_dump(odbc_result($res, 'whatever'));
?>


Expected result:
----------------
string(8) "whatever"


Actual result:
--------------
string(8) "whatever"

Warning: String is not zero-terminated (whatever) in %s on line %d
