## #55988 — Arnaud Le Blanc — 2011-10-29T11:44:27+00:00

Hi,

Closures can hold references to variables, but don't expose them to the 
garbage collector. The GC is unable to find cycles in which a closure is 
involved, and this can create memory leaks.

I've reported this problem in https://bugs.php.net/bug.php?id=60139 and posted 
a patch. Can someone please review it ? This fixes the problem by returning 
the closure's closed variables and this_ptr from get_properties (most of this 
has been copied from SplObjectStorage's get_properties). I would like to 
commit in 5.3 as well.

Best Regards,
