Well, part of the problem is that config.layer_height defaults to 0 apparently, so the layer push in the slice() method adds layers until it runs out of memory.

[lordofhyphens]

@jdevelop on the CLI, anyway, you probably want to specify the options manually or generate a Slic3r config and export it and load that on the CLI.

I don't know why the GUI config isn't being loaded.

Looks like I had found a different bug #4139 when debugging your issue by mistake.

[lordofhyphens]

@jdevelop as a short-term workaround, try setting your infill to 100% and rectilinear. Or 0% infill.
