Autocad Crash on opening file

[DGriffin91]

I'm having an issue where if I open a DXF file with dxf-rs, then save, the resulting file it crashes autocad 2016.

I'm using the latest version of dxf-rs from github.

let drawing = Drawing::load_file("input_test.dxf").unwrap();
drawing.save_file("output_test.dxf").unwrap();

Input and output test files:
test.zip

Just have a quick test. They can be loaded successfully in QCAD, LibreCAD and ODA :)
