libstdc++: [_GLIBCXX_DEBUG] Fix assignment of value-initialized iterator [PR112477]
Now that _M_Detach do not reset iterator _M_version value we need to reset it when
the iterator is attached to a new sequence, even if this sequencer is null when
assigning a value-initialized iterator. In this case _M_version shall be resetted to 0.
libstdc++-v3/ChangeLog:
PR libstdc++/112477
* src/c++11/debug.cc

sequence.

(_Safe_local_iterator_base::_M_attach): Likewise.
