1. It would help if the commands that were executed were given.
2. I suppose 101 is the line number but there is no err_handler on that line. the first use of err_handler is on line 113.

I suppose a port to jbuilder and CI using AppVeyor is desirable.

@brendanlong if you have the courage, setting up AppVeyor would also be nice. See e.g. https://github.com/Chris00/ocaml-interval/blob/master/appveyor.yml

[Chris00]

mingw works.
msvc untested (one should enable appveyor for it and fix the problems).
