Operating system:

Package: Scripting Engine problem
Bug Type: Bug
Bug description:PHP Segfaults when trying to expand an infinite operator
Description:
------------
PHP Segfaults when trying to expand an infinite operator
Test script:
---------------
$iterator = new InfiniteIterator(new ArrayIterator([0, 1, 2, 3, 4]));
var_dump(...$iterator);
echo "Still alive!";
Expected result:
----------------
Something sensible, either the script aborting to lack of memory, or
otherwise shutting down cleanly.
Actual result:
--------------
Segfaults apparently https://3v4l.org/6IRrp/segfault#tabs
