Note:

The D2-way of doing this is by using shared.


struct Test {
  shared uint* ptr;
  uint write(uint i) { (*ptr) = i; return i; }
}

void main() {
  Test test; test.ptr = cast(uint*) 0xDEAD_BEEF;
  test.write(0); test.write(0); test.write(0);
  return;
}


Also guarantees that (*ptr) is stored thrice also.

_Dmain: 
        .fnstart
        ldr     r3, .L6
        @baz
        mov     r0, #0
        str     r0, [r3]
        str     r0, [r3]
        str     r0, [r3]
        bx      lr
        .fnend



Regards,
Iain
