This happened implicitly in the past due to EX(opline) being used - or in the hybrid VM case, the implicit LOAD_OPLINE() happening as part of ZEND_VM_ENTER(). With 76d7c61 opline is used standalone and the return value of zend_interrupt_helper_SPEC ignored. Make use of it... Signed-off-by: Bob Weinand <bobwei9@hotmail.com>

I think that we should reload ex from EG(current_execute_data) as well, because the interrupt handler may have changed it

I don't object to that, though that hasn't been working since PHP 8.0. Would simplify my extension code a bit :-D
Also ZEND_VM_FCALL_INTERRUPT_CHECK() doesn't read execute_data back. Possibly both should.

Ah indeed. The HYBRID VM ignores execute_data changes too, as it will assign ex to it.
