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

[Klaus R. <kla...@rz...>]

Hi Alan,

the __construct function looks like this now:

PHP_METHOD(swfshape, __construct)
{
    SWFShape shape = newSWFShape();
    int rsrc_id = ZEND_REGISTER_RESOURCE(return_value, shape, le_swfshapep);
//    int rsrc_id = zend_list_insert(shape, le_swfshapep);
    object_init_ex(getThis(), shape_class_entry_ptr);
    add_property_resource(getThis(), "shape", rsrc_id);
    zend_list_addref(rsrc_id);
}

Commenting the zend_list_addref() has no additional effect on memory 
usage here.

Thanks
    Klaus
