cbs.event is written to just on the very next line, so if the intention of the memcpy() is to write cbs.event, it can be removed altogether.

The compiler warning is correct but the fix should just require the address-of operator (&) on the first parameter cbs.event.

When compiling DDD with a recent gcc (5.4.0 in my case), the following warning is given:

The warning seems to be valid, since the memcpy() parameters are most likely the same (dst == src), and the size is size_of_pointer.

event is unitialized (its default constructor is used; if applicable)

This patch might trigger the originally intended behavior:
