================================

I'm getting this again with dmd 2.069.

With the files below, running rdmd -g -inline main.d I get:

When removing the std.algorithm import from main.d or compiling without -inline
it works fine.

-- main.d --
import std.algorithm;
import failsinline;

void main()
{
  auto fail = new FailsInline();
  fail.failsinline();
}
-- main.d --

-- failsinline.d --
import std.algorithm : map;
import std.array : array;

class FailsInline
{
  void failsinline()
  {
    auto transform = (int i) => i;
    [0].map!transform.array;
  }
}
-- failsinline.d --
