Subject: Re: [PHP-DEV] (non)growing memory while creating anoymous functions
 via eval()
From: petrich@tronic-media.com (=?utf-8?Q?Hans-J=C3=BCrgen_Petrich?=)

Hi Terry and all
thank you very much for your response.

> The only thing that confused me about what you say that the second *doesn't* grow
Yes, about that i was [and am still :-)] also confused... why the 2nd one won't grow *non-stop*

> so I checked and it does -- just the same as the first.
Right, it grows, but not non-stop as in the 1st one.

The memory will stop growing (on my machine) at ~2491584 bytes and the loop is able to run forever,
creating each eval() furthermore uniqe ano-function's but not endless-filling Zend-internal tables.

> but this still leaves the function record itself in the function_table hash so with a non-zero reference count and this doesn't get DTORed until request shutdown
Not familar with the Zend-internals but just about so i was imaging and expecting it.

That why i [still] also confused/wondering why in the 2nd example the memory will not grow *endless*.
It seems that the function records in the function_table will be DTORed (or similar cleaned up) before request-shutdown at some point...

Could this be the case?
