Description:
------------
My result of Example #1 from http://php.net/manual/en/worker.unstack.php differs from the one in the documentation.

PHP configure line:
./configure --prefix="$HOME/local/php5" \
    --disable-cgi \
    --enable-maintainer-zts \
    --with-libdir=/lib/x86_64-linux-gnu \
    --without-pear \
    --disable-all

pthreads configure line:
./configure --prefix="$HOME/local/php5" \
    --with-php-config="$HOME/local/php5/bin/php-config"

I tested with pthreads 2.0.10 and the current git master 7d4e30a4cf.

Test script:
---------------
<?php
class Work extends Threaded {
    public function run() {
        
    }
}

$my = new Worker();
$work = new Work();
var_dump($my->stack($work));
var_dump($my->unstack($work));
?>

Expected result:
----------------
int(1)
int(0)

Actual result:
--------------
int(1)
int(1)

pthreads v2 is no longer supported, and so this issue will not be resolved. The Worker::unstack() method has new semantics in pthreads v3, where it no longer accepts an argument - it just pops the top task from the stack.

Your example code will now produce the following output:

int(1)
object(Work)#2 (0) {
}
