 New Comment:

seems something wrong with the refcount of zval in traits's 
default_properties_table[i].  

but I have not figured out what's going wrong. 

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

http://dev.daylessday.org/diff/bug60536_003.mem

So the problem is definitely not fixed yet.
