Electronic – ngspice, malloc: internal error can’t allocate -8 bytes

I am new to ngspice and trying to simulate my first circuit. I have posted my spice.net and my simulation.cmd below with a picture of my schematic. When I run the simulation I get the error message:

malloc: internal error can't allocate -8 bytes.

Does anyone know what the problem might be?

Thanks
