Where there are ?? ??, should be part of the assembly code of the engine, and instead of it there are a lot of invalid instructions. So the RAM went corrupted, and is not some bug of the engine, as I understand the processes does not have permission to overwrite the execution memory.
This smells like faulty hardware. Back everything up and test all system memory in case of potential crash.
