Actually, zval_ptr_dtor calls zval_dtor, which does much more EG(...) games than just EG(uninitialized_zval_ptr). So I guess calling zval_ptr_dtor before init_executor is unwise indeed...
    yep - but can we simply move init_executor a bit "up"?

Probably not. Can you simply fix the OnChange callback? :) NULL up the ASSERTG(callback) on time? Zeev
