RE: [PHP-DEV] Re: static members of internal classes

Hi Michael, It is not a bug. You understood proper. Internal classes are stored in regular heap and they don't use e[memory] function family. This is done, because memory allocated by emalloc is freed after each request, but internal classes should still alive in global class table. Thanks.
