A breach of immutability due to memory implicit conversions to immutable without synchronisation, maybe??

[John Colvin]

Correcting the obvious typos:

int* foo() pure {
     auto ret = new int; // A
     *ret = 3; // B
     return ret;
}

shared immutable(int)* g;

void bar() {
     immutable(int)* d = null;
     while (d is null)
         d = g.atomicLoad!(MemoryOrder.raw);
     assert(*d == 3); // D
     assert(*d == 3); // E
}

void main() {
     auto t = new Thread(&bar).start();
     immutable(int)* a = foo();
     g.atomicStore!(MemoryOrder.raw)(a); // C
     t.join;
}
