Compile boost-python tutorial with VS-2015 CTP 5 and Python 3.5a on Windows 10 TP

I'm trying to get the boost-python extension module tutorial working on a modern C++14 compiler in Windows 10. I've downloaded the latest versions of boost 1.57 and python 3.5a source using vc-14 (VS 2015 CTP 5).

I compiled python from source using VS 2015 CTP 5 and these instructions: 1.1.3.3. Windows.

I've run the command

bootstrap.bat && b2 python

from the boost project folder c:\boost

This is the user-config.jam file in my home directory:

using msvc : 14.0 : C:\\Program\ Files\ (x86)\\Microsoft\ Visual\ Studio\ 14.0\\VC\\bin\\cl.exe ;

using python                                                                                     
        : 3.5                                        # Version                                                            
        : C:\\python35a3\\PCBuild\\win32\\python.exe # Python Path                              
        : C:\\python35a3\\include                    # include path                                   
        : C:\\python35a3\\libs                       # lib path                                       
        : <define>BOOST_ALL_NO_LIB=1                                                                 
        ;  

Running bjam in the tutorial directory results in an incompatibility when creating the pdb file:

The command producing the error output is:

The link command seems to be consistent with the way python and boost are compiled (32 bit on the same compiler version).

Is there an way to diagnose where this error originated?
