New Revision: 269836
URL: http://svnweb.freebsd.org/changeset/base/269836

Log:
  MFC r269740:
  
  Pull in r214736 from upstream libc++ trunk (by Marshall Clow):
  
    Fix PR#20520 - predicate called too many times in list::remove_if.
    Add tests for list, forward_list, and the std::remove_if algorithm
  
  This fixes an issue where std::list<>::remove_if() and remove() could
  erroneously visit elements twice.
