Confirmation of bug in 5.1.4 for session_regenerate_id()

I have not dug super deep into this problem but it seems as though if I try to call session_regenerate_id() after having set session.save_path with custom values, i get an error. My guess is that session_regenerate_id() is having issues with the save_path var. This is my test script: file: ../htdocs/test.php <? ini_set("session.save_path", ";666;../application/var/sessions"); session_start(); $id_before = session_id(); if ((++$_SESSION['counter'] % 5) == 0) {

    session_regenerate_id(true);

} echo "<pre>SESSION ID BEFORE: " . $id_before . "\n"; echo "SESSION ID AFTER : " . session_id(); ?> The first 5 times it runs, it works fine... which means the file was created with the proper permissions and at the proper location. The 5th run produces this: SESSION ID BEFORE: 36236b948b074164d5344184a79ceeff SESSION ID AFTER : 759d5771cbcd3535c03660cc056385df Warning: Unknown: open(../application/var/sessions/sess_759d5771cbcd3535c03660cc056385df, O_RDWR) failed: No such file or directory (2) in Unknown on line 0 Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (;666;../application/var/sessions) in Unknown on line 0 My permission on that directory are 777.. so technically there should be no problem. /home/ralph/development/vhosts/framework.dev.smashlabs.com/application/var drwxrwxrwx 2 ralph users 4096 Jul 12 13:30 sessions
