Description:
------------
The stream_notification_callback is being used inside of a class and tries to modify object variables. Inside of the callback function the varibles are returned in the right way. After leaving the function, changed variables are destroyed. (Example 1)

Surprisingly if the variable is modified outside of the switch statement, but still inside of the stream_notification_callback, variable value changes and cannot be overwritten with the following statements. (Example 2)
