**Affected subclause:** [[algorithms.general]](algorithms.general)  


**Change:** Result state of inputs after application of some algorithms[.](#1.sentence-1)

  


**Rationale:** Required by new feature[.](#1.sentence-2)

  


**Effect on original feature:** A valid C++ 2003 program may detect that an object with a valid but
unspecified state has a different valid but unspecified state with this
revision of C++[.](#1.sentence-3)

For example, std​::​remove andstd​::​remove_if may leave the tail of the input sequence with a
different set of values than previously[.](#1.sentence-4)
