Fatal Error with conditional class definition.

[tuccen]

With Zend Framework the class definition of the Zend_Exception takes care of the php version and so php < 5.3 triggers an Fatal Error beacause both defnitions are in the same file.
Please have a look at  ZF-8984

To be more general, the issue is with conditional creation of classes. As an example:

if (version_compare(PHP_VERSION, '5.3.0', '<')) {
    class My_Exception extends Exception
    {
        protected $previous;
        public function __construct($message = '', $code = 0, Exception $previous = null)
        {
            $this->previous = $previous;
            parent::__construct($message, $code);
        }
        public function getPrevious()
        {
            return $this->previous;
        }
    }
} else {
    class My_Exception extends Exception {}
}

In such cases, xcache is attempting to cache two separate class definitions for the same class name, and thus creating an error condition.

In other opcode caches such as APC and Zend Optimizer, only the class definition for the matching condition is cached, which is the appropriate behavior.

can u pls try 1.3.0?

[weierophinney]

I can confirm that in 1.3.0, running under either PHP 5.2.12 or 5.3.0, the issue does not present.

I've tried installing an XCache 1.2.2 version against PHP 5.2.12, but cannot get it to compile, unfortunately, so cannot verify the reporter's original issue.
