The assignment of mas->min and mas->max is wrong. mas->min and mas->max should represent the range of the current node. After mas_ascend() returns, mas-min and mas->max already represent the range of the current node, so we should delete these assignments of mas->min and mas->max.

Please fully describe the user-visible effects of the flaw, especially when proposing a -stable backport.
