Description:
------------
The code below should be fairly self-explanatory. Invoking a reflection of the 
__invoke method of the Closure class more than once per reflection instance 
causes a segfault. This happens regardless of context or argument parameters 
passed to ReflectionMethod::invokeArgs(). Can't imagine this is a common use case 
but thought I'd share anyway.

PHP Version is 5.3.14.

I don't have php configured to get a backtrace at the moment, and my .ini is 
pretty average. If you can't reproduce it with the script below I'll look into it 
more.

Test script:
---------------
<?php

$closure1   = function($val){ return $val; };
$closure2   = function($val){ return $val; };

$reflection_class   = new ReflectionClass($closure1);
$reflection_method  = $reflection_class->getMethod('__invoke');

$arguments1         = array('hello');
$arguments2         = array('world');

// Invoking once is OK...
print $reflection_method->invokeArgs($closure1, $arguments1);

if(true){   
    // But don't do it again!
   #print $reflection_method->invokeArgs($closure1, $arguments1);
    
    // Using different arguments per invokation makes no difference :(
   #print $reflection_method->invokeArgs($closure1, $arguments2);
    
    // Doesn't matter if you attempt to invoke a different closure with the same reflection.
    print $reflection_method->invokeArgs($closure2, $arguments1);
}

?>

Expected result:
----------------
"helloworld" printed

Actual result:
--------------
Segmentationfault
