I think I've found the memory leaking case that can be fixed by this PR ([Godbolt link](https://godbolt.org/z/dWeqsGM7n)).

Could you add a new `.pass.cpp` to `libcxx/test/libcxx/containers/sequences/vector/vector.cons` which asserts that memory leak doesn't raise from this constructor when an exception is thrown?
