Re: [Ming-dev] Memory problem with the php extension ?

[Alan B. <abo...@ma...>]

Hi Klaus,

I was writing you a comment on bugzilla.... but still waiting the 
account creation confirmation... here's what i wrote:

If you comment the following line, in PHP_METHOD(swfshape, __construct) 
method:
zend_list_addref(ret);

The destructor is well called (verified with a printf in the 
destructor). BUT, the PHP OBJECT doesn't seem to be freed by php   
garbage collector. See what i get now:

Beginning of script : 57368 bytes

End of script : 769960 bytes

So, there are still "memory leaks".

Thanks,
Alan
