--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced:
```
struct vector
{
vector& operator=(vector&& __x)
{
return *this;
}
};
struct tree_node {
vector childs;
unsigned char pad[7];
tree_node(){}
};
tree_node mcts_root;
void find_Horner_MCTS_expand_tree () {
mcts_root = tree_node();
}
```
Compile at -O2 -Wall is enough to reproduce the failure.
Note using unsigned short or unsigned int instead of unsigned char allows it to
work.
