Description:
------------
No data is inserted when bindParam is used with PDO::PARAM_LOB in BLOB/CLOB types. It works if the BYTE/TEXT types are used instead.

PHP Version: 5.8.8
IBM/Informix-Client SDK Version: 4.10.UC2DE
PDO Informix Version: 1.3.1
S.O.: reproduced in Ubuntu 12.04 and RedHat EL5


Test script:
---------------
  
  // $con has a valid PDO Informix connection
  $con->exec('CREATE TABLE test_lob (test_blob BLOB, test_clob CLOB)');

  $stmt = $con->prepare('INSERT INTO test_lob (test_blob, test_clob) VALUES (?, ?)');

  file_put_contents('/tmp/test_file_1.tmp', 'test content 1');
  file_put_contents('/tmp/test_file_2.tmp', 'test content 2');

  $fp1 = fopen('/tmp/test_file_1.tmp', 'rb');
  $fp2 = fopen('/tmp/test_file_2.tmp', 'rb');

  $stmt->bindParam(1, $fp1, PDO::PARAM_LOB);
  $stmt->bindParam(2, $fp2, PDO::PARAM_LOB);

  $stmt->execute();



Expected result:
----------------
A row has to be inserted with values in the two fields.

Actual result:
--------------
After the execution no row has been inserted. No error is produced.
