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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=62991&edit=1
