--- Comment #5 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I am not 100% sure but I think the problem is related to this code (note I
added that asm comment there):
```
V *P = u.i;
V *E = P + InlineSlots;
for (; P != E; ++P) {
if (P->v != EmptyKey) {
TmpEnd->v = P->v;
++TmpEnd;
}
}
Small = false;
//asm("":"+m"(*this)::"memory");
u.o = LargeRep{new V[128], 128};
```
The problem is most likely the read from u.i is happening after the store to
u.o.
