These five functions referenced in zend_execute.c are not defined, causing compilation failure:

 zend_ptr_stack_get_arg
 zend_ptr_stack_clear_multiple
 zend_assign_to_variable_reference
 zend_assign_to_variable_reference
 safe_free_zval_ptr

Also, one function used in basic_functions.c is not defined:

 is_numeric_string

During compilation, warnings about the above are produced, but during final linking as static Apache module, fatal errors occur:
