Length is incorrectly memcpy'ied over

The implementation implements copy constructors and operators as memcpyies.
This is not ok as the type is not trivially copyable

The IPC encoding and decoding just memcpyies the memory over to other process.
This is not ok as the type is not trivially copyable.
This is not ok if "calculated" types are copied, as that results in wrong decoding.
