[PHP-BUG] Bug #60139 [NEW]: Anonymous functions create cycles not detected by the GC

2011-10-26 Thread lbarn...@php.net 
From: 
Operating system: 
PHP version:  5.4.0beta2
Package:  Performance problem
Bug Type: Bug
Bug description:Anonymous functions create cycles not detected by the GC

Description:

In the following Script 1 and Script 2, the created objects are not
destructed until the engine shutdowns because of a reference cycle.

The objects hold a reference to an anonymous function that itself hold a
reference to the object.

It seems that the garbage collector is unable to break the cycle.

Script 3 doesn't leak memory because the anonymous function doesn't hold a
reference to the object.

Test script:
---
# Script 1 (leaks with php5.4)

x = function() {};
}
}

echo memory_get_usage(), "\n";

for ($i = 0; $i < 1000; ++$i) {
new Foo;
}
gc_collect_cycles();

echo memory_get_usage(), "\n";
?>

# Script 2 (leaks with php5.3)

x = function() use ($self) {};
}
}

echo memory_get_usage(), "\n";

for ($i = 0; $i < 1000; ++$i) {
new Foo;
}
gc_collect_cycles();

echo memory_get_usage(), "\n";

?>

# Script 3 (no leak)

x = get_fun();
}
}

function get_fun() {
return function() {};
}

echo memory_get_usage(), "\n";

for ($i = 0; $i < 1000; ++$i) {
new Foo;
}
gc_collect_cycles();

echo memory_get_usage(), "\n";
?>

Expected result:

Memory usage before and after is approximatel the same:

121040
121152

Actual result:
--
Objects are never freed and memory usage increases:

120724
417640
