How do you see that? That 'last leak repeated 18 times' doesn't mean the
pointer got freed 18 times, but rather, that a leak from zend_hash.c(461)
repeated itself 18 times...
There's no magical way of solving this, other than trying to cut down the
script to the smallest piece of code that still leaks, and then trying to
figure out what causes the leak (or sending this cut-down piece of code to
php-dev for help...)
