--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
In convert_for_assignment we have:
```
/* The Plan 9 compiler permits a pointer to a struct to be
automatically converted into a pointer to an anonymous field
within the struct. */
if (flag_plan9_extensions
&& RECORD_OR_UNION_TYPE_P (mvl)
&& RECORD_OR_UNION_TYPE_P (mvr)
&& mvl != mvr)
{
tree new_rhs = convert_to_anonymous_field (location, type, rhs);
if (new_rhs != NULL_TREE)
{
rhs = new_rhs;
rhstype = TREE_TYPE (rhs);
coder = TREE_CODE (rhstype);
ttr = TREE_TYPE (rhstype);
mvr = TYPE_MAIN_VARIANT (ttr);
}
}
```
I suspect convert_to_anonymous_field is not doing the same thing as `&b->f`
would do for the qualifiers.
