 New Comment:

Further info: the crash does NOT occur if the DSN string is changed to
"mysql://..." instead of "mysqli://..." (this also seemed to be the case
in similar bug #48922)

OK, for the record then, that case was reproducible for me with
5.2.11-dev snap 200908101630. Backtrace similar to the first one opening
the bug.

NEVER ever email me privately test cases. Here's the script you sent
me:

<?php

/*
CREATE TABLE _session_data (
  id char(32) NOT NULL,
  expiry int(10) unsigned NOT NULL,
  data text NOT NULL,
  PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
*/

require_once 'HTTP/Session2.php';

$dsn = 'mysqli://user:pass@localhost/dbname';

$options = array();
$options['dsn']   = $dsn;
$options['table'] = '_session_data';

HTTP_Session2::setContainer('MDB2', $options);
HTTP_Session2::start('mysess');

?>

Installed PEAR packages to make it happen:
HTTP_Session2      0.7.2   beta
MDB2               2.5.0b2 beta
MDB2_Driver_mysqli 1.5.0b2 beta

And as expected: We really need proper, short, reproducing script. Now
the problem might be anywhere..

In the future: PLEASE add the backtraces in separate comments. Now it's
pretty hard to see which is which.

N.B. this occurs with both apache2 and CGI SAPIs.
