Missing alignment can also throw the compiler off:

----
alias T = int;

enum T a = 0x01_01_01_01;
enum T b = 0x02_02_02_02;

struct S
{
     byte[13] padding;
     align(1) T x = a;
}

shared S s;

import core.thread: Thread;

void write()
{
     bool flip = false;
     foreach (i; 0 .. 1_000_000)
     {
         if (flip) s.x = a; else s.x = b;
         flip = !flip;
     }
}

void main()
{
     auto t = new Thread(&write);
     t.start();
     foreach (i; 0 .. 1_000_000)
     {
         T r = s.x;
         assert(r == a || r == b); // fails
     }
     t.join();
}
