Parse error: error: 'Invalid VCD data'

I have found this extreme VCD: https://github.com/GordonMcGregor/vcd_parser/blob/master/sample.vcd

I get { error: 'Invalid VCD data' }, while parsing this.

That example VCD file is the example from the IEEE.1364-2005 specification. See 18.2.4 Four-state VCD file format example chapter
