Description:
------------
Collection creation errors are displayed if display_errors and
error_reporting are set appropriately, but a subsequent oci_error()
returns false, so error trapping won't display the problem.

After OCITypeByName() fails in php_oci_collection_create(),
php_oci_collection_close() is called.  The line
  zend_list_delete(collection->connection->rsrc_id)
causes the subsequent oci_error() function line
  connection = (php_oci_connection *) zend_fetch_resource(&arg TSRMLS_CC, -1, NULL, NULL, 1, le_connection);
to return a null pointer.


Reproduce code:
---------------
<?php
$c = oci_connect('hr', 'hrpwd', '//localhost/XE');

$collection = oci_new_collection($c, "BOGUS");
if (!$collection) {
    $m = oci_error($c);
    echo "Error: ", $m["message"];
}
?>

Expected result:
----------------
  Error: OCI-22303: type ""."BOGUS" not found

Actual result:
--------------
  Error:
