$source is of type FFI\CData, but the property $source was declared to be of type FFI\CArray. Are you sure that you always receive this specific sub-class here, or does it make sense to add an instanceof check?
                                                                                                                                                                                                                                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Our type inference engine has found a suspicous assignment of a value to a property.
This check raises an issue when a value that can be of a given class or a super-class
is assigned to a property that is type hinted more strictly.


Either this assignment is in error or an instanceof check should be added for that assignment.
