I cannot reproduce your problem using the information you've given.
That structural data runs just fine and gives sensible output on both
Windows and linux.

When making a bug report, you should include the information discussed
in http://bruceravel.github.io/demeter/pods/bugs.pod.html.  Without the
information in the error log and without an actionable recipe for
replicating the problem, there is simply nothing that I can do to help.
