That means we need to set _M_finish == _M_start so that the destructor doesn't try to destroy any elements. libstdc++-v3/ChangeLog: PR libstdc++/120367 * include/bits/stl_vector.h (_M_range_initialize): Initialize _M_impl._M_finish. * testsuite/23_containers/vector/cons/from_range.cc: Check with a type that throws on construction. exceptions during construction.
