 New Comment:

This seems to also affect generators without finally.

Maybe something like this is also the root cause for the segfault here https://bugs.php.net/bug.php?id=75351

Description:
------------
See example. It doesn't continue the generator anywhere, it just exists.

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

$gen = (function () {
    yield 42;

    try {
    } finally {
        exit;
    }
})();

$gen->send("x");

Expected result:
----------------
Clean exit.

Actual result:
--------------
Fatal error: Cannot resume an already running generator.
