The problem in 4.1 was the same as in 4.0 - fix_fields() not called for created Item_ref. 
The fix is similar too - initialize Item_refs in ctor (but don't interfere with cases when 
Item_ref is used by subselects).

In Item_ref::Item_ref set maybe_null (and other fields fix_fields sets) to be the 
same as in (*ref), because Item_ref::fix_fields() will not be called.  Previously 
maybe_null was 0 always and this produced a bogus state where 
maybe_null==0 && is_null() == true 
which broke evaluation for some upper-level Items, like AND and OR.
