Same code as above, very slightly simplified.
-----------------
import std.typecons  : Tuple;
import std.array     : appender;
import std.stdio     : writeln;

struct S {
  Tuple!(uint, double)[] _data;
  alias _data this;
}

private auto gen(K, V)(V[K] data) {
  alias Tuple!(K, V) T;
  auto app = appender!(T[]);
  foreach(k, v; data) app.put(T(k, v));
  return app.data;
}

auto s(double[uint] data) {
  return S(gen!(uint, double)(data));
}

void main() {
  static S s1 = s([1: 12.0, 5: 4.6, 3: 9.99]);
  S s2        = s([1: 12.0, 5: 4.6, 3: 9.99]);
  writeln(s1);
  writeln(s2);
}
------------------
PS E:\DigitalMars\dmd2\samples> rdmd -g bug.d
[Tuple!(uint,double)(0, nan), Tuple!(uint,double)(0, nan),
Tuple!(uint,double)(0, nan)]
[Tuple!(uint,double)(1, 12), Tuple!(uint,double)(3, 9.99),
Tuple!(uint,double)(5, 4.6)]

If we remove the static, it works.

If we replace the appender by an array in:

import std.typecons  : Tuple;
import std.array     : appender;
import std.stdio     : writeln;

struct S {
  Tuple!(uint, double)[] _data;
  alias _data this;
}

private auto gen(K, V)(V[K] data) {
  alias Tuple!(K, V) T;
  T[] app;
  foreach(k, v; data) app ~= T(k, v);
  return app;
}

auto s(double[uint] data) {
  return S(gen!(uint, double)(data));
}

void main() {
  static S s1 = s([1: 12.0, 5: 4.6, 3: 9.99]);
  S s2        = s([1: 12.0, 5: 4.6, 3: 9.99]);
  writeln(s1);
  writeln(s2);
}
PS E:\DigitalMars\dmd2\samples> rdmd -g bug.d
[Tuple!(uint,double)(1, 12), Tuple!(uint,double)(5, 4.6),
Tuple!(uint,double)(3, 9.99)]
[Tuple!(uint,double)(1, 12), Tuple!(uint,double)(3, 9.99),
Tuple!(uint,double)(5, 4.6)]

If we remove the static:
PS E:\DigitalMars\dmd2\samples> rdmd -g bug.d
[Tuple!(uint,double)(1, 12), Tuple!(uint,double)(3, 9.99),
Tuple!(uint,double)(5, 4.6)]
[Tuple!(uint,double)(1, 12), Tuple!(uint,double)(3, 9.99),
Tuple!(uint,double)(5, 4.6)]
