I would like to report another issue: if I use the aop extension and I use a generator function (which yields), like the following (taken from the manual):

<?php
function gen_one_to_three() {
    for ($i = 1; $i <= 3; $i++) {
        // Note that $i is preserved between yields.
        yield $i;
    }
}

$generator = gen_one_to_three();
foreach ($generator as $value) {
    echo "$value\n";
}
?>

The following code will result in an infinite loop:

1 1 1 1 1 1 1 ... Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 448 bytes)

So I suppose it is a bug cause when I disable the extension, everything works fine:

1 2 3
