The column id check in VSlotRef::execute function before is too strict for fuzzy test to continuously produce random query. Temporarily loosen the check logic. Moreover, there exists some careless call to VExpr::get_const_col, it might return a nullptr but not every function call checks if it's valid. It's an underlying problem.
