This fails whenever the size is greater or equal to the amount of memory required :(

Hum nevermind that, got confused by the IDE behavior. Anway this emplace function crashes when I call it with a very meaningless callstack.

This works for me:

import std.conv;
class C {
  int i;
  this() { i = 42; }
}
unittest {
  void[__traits(classInstanceSize, C)] data = void;
  auto c = emplace!C(data[]);
  assert(c.i == 42);
}
