Boost failed to compile test in graph lib due to the error C2499.

[1518134125@…]

We tried to build and run graph test for Boost. It failed to build due to the error C2499: 'boost::array_binary_tree_node<RandomAccessIterator,ID>::children_type::iterator': a class cannot be its own base class. Could you please help take a look at this? Thanks!

Reproduce steps:

1. git clone -c core.autocrlf=true --recursive ​https://github.com/boostorg/boost.git D:\Boost\src
2. Open a VS 2015 x86 command prompt and browse to D:\Boost\src
3. .\bootstrap
4. .\b2 headers variant=release --build-dir=..\out\Release --address-model=32
5. .\b2 variant=release --build-dir=..\out\Release --address-model=32
6. .\b2 -j4 variant=release --build-dir=..\out\x86rel libs\graph\test

Expected result:

All tests passed

Actual result:
