import std.stdio;

struct Y {
  private immutable(int)[] _data;
}

struct CFS {
  double x = 5;
  Y growth;
}

void main() {
  auto s = CFS(1.0);      // crash
  //auto s = CFS(1, Y()); // crash
  //auto s = CFS(1, Y([])); // works
  writeln(s);
}

If x is an int there is no problem.
If s is not accessed there is no problem, so it dies in the writeln call.
