'serializationLength' but non-virtual destructor with custom message

edit

I have created a ros node that is a subscriber and publisher. I have also created a message type called "patd" which has the following types: int32 distance String Pattern_no

after doing rosmake the custom message class is created and I have done the include accordingly, "depth_viewer/patd.h".

my problem is that when ever I try to use the custom message I get an error when running the node, "segmentation fault" as i'm working with the kinect.

this is the error I get regarding my custom message:

Class '[C@254fb0' has virtual method 'serializationLength' but non-virtual destructor
