Description:
------------
Verions: PDO-1.0.3
         PDO-INFORMIX-1.2.6
         PHP-5.2.8-r1

I dont know why or when, but now PDO dont report errors in queries to the function set with set_error_handler().

I have to force the attribute
$pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );

With this It reports errors but dont complete the node 'query' in the var errcontext (Param of my error handler function)



Reproduce code:
---------------
...
function my_err_hand ($errno, $errmsg, $filename, $linenum, $errcontext) {
  if(isset($errcontext['query'])) {
    echo "query: " . $errcontext['query'];
  } else {
    echo "query was not set";
  }
}

set_error_handler('my_err_hand');
...

$pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );

$pdo->query("SELECT false_column from some_table");





Expected result:
----------------
query: SELECT false_column from some_table

Actual result:
--------------
query was not set
