php 5.3 - Non-deterministic object reference bug in PHP 5.3.X -

-

as of yesterday (perhaps after recent php update?), i'm getting strange non-deterministic bugs in php 5.3.3. these appear in our production server in php 5.3.2 well.

the errors amount fatal error: uncaught exception 'errorexception' message 'attempt assign property of non-object' in various parts of code base. generally, error line like: $this->foo = $bar in __construct() call.

$this not found in constructor?!

i have no idea going on. ideas? possibly regression of bug?: http://bugs.php.net/31525

edit: should mention, refreshing script after little while, absolutely no changes code, makes work again. hence non-deterministic.

edit 2: furthermore, while php set log tiniest of errors, , is logging other errors occur, error not logged in log file. brings me think looking @ php engine dependency error.

well, looks bug...

here's relevant bug reports:
