Weird LDC error on mac

[Bogdan]

Hey everyone!

After a long time, I wanted to build my Vibe project on Mac using 
LDC, and I got weird compiling errors that made no sense and 
didn't know how to debug or fix. Does anyone have any tips on how 
I should make it work?

           _d_arraysetctor(this._outer_[], data)
lowered   this._outer_[] = data =>
           _d_arraysetctor(this._outer_[], data)
