Basically a window popped up and say something along the lines of "blockland.exe - buffer overrun detected - terminating" (from memory of seeing it).The way I cause it is if I have a long history of functions in the console window and press the up arrow about 6-8 times, it will crash with the error.
Console log please
How long a history are you talking about?
Not necessary. The bug is clearly within the engine.
