I'm seeing this as well, another backtrace: http://friendpaste.com/7gEu3sIEwJeE0YcDGyMzKe

In my case it is the Writing\\SetPropertyMethodsTest that crashes. All SetPropertyDynamicRebindingTest passed without problems (well, with some failures)

Another backtrace on the same issue, this time with Writing\AddMethodsTest: http://friendpaste.com/8UaYMJIo7XZxHb6IsTpFs

Looks like common pattern is constructor:

zend_call_method_with_1_params(&mdate_object, php_midgard_datetime_class, &php_midgard_datetime_class->constructor, "__construct", NULL, date);

zend_call_method_with_0_params(&zvalue, ce, &ce->constructor, "__construct", NULL);
