A more simple test: <?php trait A { private $hello = 0; } class BaseWithTPropB{ use A; } class SubclassB extends BaseWithTPropB { use A; } $b = new SubClassB; var_dump($b); ?> plz run valgrind like: USE_ZEND_ALLOC=0 valgrind --db-attach=yes --leak-check=full php test.php ------------------------------------------------------------------------ [2011-12-19 04:53:11] laruence@php.net Gron, ignore the assigment, I just want to get your attention, so let's diag this one again :) thanks ------------------------------------------------------------------------ [2011-12-19 04:07:46] laruence@php.net found while diagnosing #60536 ------------------------------------------------------------------------ [2011-12-19 04:05:56] laruence@php.net Description: ------------ Valgrind complains about invalid read and writes in the tests: http://dev.daylessday.org/diff/bug60536_001.mem http://dev.daylessday.org/diff/bug60536_003.mem So the problem is definitely not fixed yet.
