Description:
------------
or at least that's my guess.

when calling $PDObj->exec()
"sql statement here;" works as expected
"sql statement here; " causes a MySQL syntax error
(note the trailing space)

Reproduce code:
---------------
$sql = "SELECT * FROM some_table; ";
if (FALSE === $res = $PDO->exec($sql)) {
  $err = $PDO->errorInfo();
  echo "Error: {$err[1]}: {$err[2]}\n";
}



Expected result:
----------------
no error

Actual result:
--------------
Error: 1064: You have an error in your SQL syntax near '; ' at line 1
