includes/bootstrap.inc:

/**
 * Return all messages that have been set.
 *
 * As a side effect, this function clears the message queue.
 */
function drupal_get_messages() {
  $messages = drupal_set_message();
  $_SESSION['messages'] = array();

  return $messages;
}

$_SESSION['messages'] = array(); does not clear the array for some reason. I am guessing the bug is in PHP5 itself.

unset($_SESSION['messages']); does not clear it as well, the only thing I have got to work is session_unregister('messages');

PHP 5.0.4:

I am using files for session saving.

I'm going to assume that since its been 6 months and we're at 4.6.6 that this is no longer an issue. Correct me if I'm wrong.

I have the same problem under 4.6.6.

Maybe related to the fact that session variables can be lost when header('Location: ') is invoked?

Could you please try this?

In includes/bootstrap.inc, find:

session_start();

after that line, add:

register_shutdown_function('session_write_close');

or try this?

In includes/common.inc, find:

header('Location: '. $url);

BEFORE that line, add:

session_write_close();
