Yes I also faced that problem. The current execute() function accepts an op_array and initializes the execution context from that (execute_data + CVs + Ts).
So I added a new function execute_ex() which takes that execution context directly. The execute() function now works by initializing the execute_data using a new zend_create_execute_data_from_op_array() function and then calls execute_ex() with it. The most relevant commit for this change is https://github.com/nikic/php-src/commit/f627be52540738e124da7cb1566d7f60a2b6a48b.
