Hello Aaron,
first of all a warm welcome on our mailinglist!
I quickly tried and got the same behavior, so it is definitely not your
fault! After I compiled with "-no_check" it even runs without issue, so
maybe there is a problem in of the invariants in the wrapper.
In case you plan to actively use it I can take a look and fix it. But
as you might see from the activity on this list and also in the
compilers repository, there is active project using liberty eiffel
these days. That's also the reason why the developers lost interest in
the last years, as maintaining a compiler project without users is not
very satisfactory. That said I can also say, that I am still convinced
that Eiffel - and its GNU dialect LibertyEiffel is technically the best
programming language I know, but we have a lack of libraries and users.
In case you want to change that and start a project using liberty I
would wake up from hibernation and support you at my very best!
Regards,
Rapha
