Precompilation failure on Julia nightly

[bkamins]

I get the following warning:

WARNING: Method definition (::Missings.PassMissing{F})(Any...) where {F} in module Missings at /home/bkamins/.julia/packages/Missings/sx5js/src/Missings.jl:192 overwritten on the same line (check for duplicate calls to `include`).
  ** incremental compilation may be fatally broken for this module **

@nalimilan - do you know what could cause this?

Maybe a Julia bug with generated functions? Probably worth reporting.

I have the same in KristofferC/Crayons.jl#45. Who do you think we should report to?
