If Apache or a similar SAPI receives a signal during PHP processing
it calls zend_shutdown() without calling shutdown_executor().
#65463: If a module like Gearman or Memcached is loaded,
in the unfixed version it is unloaded by zend_destroy_modules() before the
CG(CLASS_TABLE) is destructed. When CG(CLASS_TABLE) is destructed,
any pointers to methods (specifically around destruction) in the unloaded
module's .so are now dangling and the process segfaults.
#66036: Any subclasses of an internal class like ArrayObject need
to be destructed in order: subclass first and then the internal class. In the
unfixed version zend_shutdown() clears the CG(CLASS_TABLE) from the head
of the list onwards, so internal classes are destructed first and user-defined
classes last. Internal classes are alloc/deallocated with malloc/free while
user-defined classes with emalloc/efree. If there's shared data between them
then efree() could be called instead of free() leading to a seg-fault.

* call-frame:
Simplify call-frame handling
Removed EG(active_symbol_table) and use corresponding value from EG(current_execute_data)
Use values from current_execute_data instead of globals where possible
Removed EG(called_scope) and use corresponding value from EG(current_execute_data)
Removed EG(in_execution). If EG(currentent_execute_data) is not NULL we are executing something.
Removed EG(opline_ptr) and use corresponding value from EG(current_execute_data)
Removed EG(active_op_array) and use corresponding value from EG(current_execute_data)
Uinified call frame handling for user and internal functions. Now EG(current_execute_data) always point to the call frame of the currently executed function.
Fixed cleanup of incompleytely passed parameters
Prohibited parameter redefinition
Fixed support for extra arguments in conjunction with variadiv argument. Use compile time flags to check if we call constructor and result of ZEND_NEW is used or not.
Fixed uninitialized variables
Optimization
Changed zend_execute_data layout to reduce memory overhead
Help C compilet to do the better job optimizing target code
Use fast comparison for (func->type == ZEND_USER_FUNCTION || func->type == ZEND_EVAL_CODE)
Keep extra args in the same VM stack segment (after all CV and TMP vars)
Refactoring: merge call_frame and end_execute_data into single data structure. Keep only single copy of each argument on VM stack (previously ZE kept two copies of each arguments for user functions)
Refactoring: use call_frames instead of call_slots
