Right. Here we go. I had testcased it incorrectly.

The code to reproduce the error is 


struct Test {
  uint* ptr;
  uint write(uint i) { volatile (*ptr) = i; return i; }
  static Test opCall() { // it has to be returned by a function call, otherwise
the error doesn't happen
    Test res;
    res.ptr = cast(uint*) 0xDEAF_D00D;
    return res;
  }
}

void main() {
  auto mat = Test();
  asm { "@baz"; }; // added to make sure it's the correct assembly this time
  mat.write(0); mat.write(0); mat.write(0);
  return;
}

And the assembly is here http://paste.dprogramming.com/dpag1p5d
