Description:
------------
If you create a generator-closure inside of a function and call that function
before returning it, it'll cause memory corruption causing a segfault.
Test script:
---------------
<?php
function test( array $array )
{
$closure = function() use ( $array ) {
var_dump( $array );
yield "hi";
};
return $closure(); // if you return the $closure and call it outside this function it works.
}
$generator = test( array( 1, 2, 3 ) );
foreach( $generator as $something ) {
// Segmentation fault: 11
}
Expected result:
----------------
array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) }
Actual result:
--------------
Segmentation fault: 11
