Compiler bug on dll call

[stugol]

The code here throws a compiler bug.

[asterite]

Good catch. I reduced it to this:

lib LibC
  fun foo(...)
end

LibC.foo(out x)

Basically, the use of out with variadic parameters. That shouldn't compile (because there's no way the compiler can figure out the type of x). As a workaround, you can use, in your case:

  def self.get_terminal_size
    screen_size = uninitialized Int32
    C.ioctl(0, tIOCGWINSZ, pointerof(screen_size))
  end
