See http://erlang.org/pipermail/erlang-questions/2018-June/095614.html

OTP-21.0 sees the entire file drivers rewritten. The bug you have seems 
to have been reported to the OTP team during OTP-21-rc2.

I don't know exactly what happened between OTP-21-rc2 and OTP-21.0, and 
if you'd need to run with a rebar3 built specifically on OTP-21.0 for 
things to work fine.
