In SelectList.reset(), we call reset() on each select list item's expr. reset() is supposed to remove implicit casts, by returning the reset expr with implicit cast exprs removed from the tree. Previously SelectList.reset() ignored the return value of the calls to Expr.reset(), meaning that if the top-most expr of the select list item is an implicit cast, it won't actually get removed, which causes problems with analysis since implicit casts are always treated as pre-analyzed. The solution is to set the select list item's exprs to the return value of reset().
