Link: http://git.php.net/?p=php-src.git;a=commitdiff;h=d6505acbf5ff6db0e9e19cdba121183d9563bad5 Log: Fixed bug #64821 Custom Exceptions crash when internal properties overridden If user inherits Exception and overrides the properties to arbitrary data types, or simply doesn't run parent::__construct(), here we go. Just convert everything to the appropriate data type, like Exception::__toString() does.
