MWE failure in Libdl

What do you get?

fcfun(x::Int, y::Int) = 1
function cfcfun()
    cf = @cfunction(fcfun, Int, (Int, Int))
    ccall(cf, Int, (Int, Int), 1, 2)
end
@test @interpret(cfcfun()) == 1

On master I get

If it works for you, what is your @code_lowered cfcfun()?

Fixed in #107

[KristofferC]

That MWE fails for me. Not sure why the original one is not... Am I running things compiled that shouldn't be?

[timholy]

Not sure. But it's reassuring you mostly see the same thing. I am getting a little worried about the apparent differences in installations.

[KristofferC]

I tried with master as well, perhaps the code path on Windows is different from Linux?
