Could you give me more information on what the core problem is so that I can try to avoid it? Thanks, - Tim Macinta ------------------------------------------------------------------------ [2006-03-20 00:17:24] mike@php.net Sorry, won't get fixed for PHP-4. ------------------------------------------------------------------------ [2006-03-20 00:05:14] twm at twmacinta dot com Description: ------------ Hello, I have a set of two classes which are used together and which work fine initially but which result in memory corruption after being instantiated 32767 times. I have attached the URL of a sample script which demonstrates the problem since I wasn't able to reproduce it in 20 lines or less. I ran the program through Valgrind to see if it could ferret out more specifics, but it didn't report any errors.
