I think the change in behaviour is a consequence of
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53263#c11

Potentially we could disable the partitioning checks when input iterators are
used (unless _GLIBCXX_DEBUG_PEDANTIC is defined) or explicitly check for input
iterators and give a better diagnostic.
