PR libstdc++/112349 libstdc++-v3/ChangeLog: * include/bits/ranges_algo.h (__min_fn::operator()): Turn local object __tmp into a reference. * include/bits/ranges_util.h (__max_fn::operator()): Likewise. * testsuite/25_algorithms/max/constrained.cc (test04): New test. * testsuite/25_algorithms/min/constrained.cc (test04): New test.
