12626,Building boost with Python and MPI failed (MSVC),MailMr_S@…,Matthias Troyer,"I don't which component is not working.

I've checked out https://github.com/boostorg/boost.git and create the configuration file:
{{{
using python : 3.5 : E:/Work/Tools/python-3.5.2.3-portable32/python-3.5.2/python.exe
    : E:/Work/Tools/python-3.5.2.3-portable32/python-3.5.2/include
    : E:/Work/Tools/python-3.5.2.3-portable32/python-3.5.2/libs ;

using mpi ;
}}}

I've installed python 3.5 and Microsoft MPI v7.1 (and SDK). Now I try to build boost:
{{{
b2.exe --user-config=user-config.jam -j 4 --toolset=msvc-12.0 --build-type=complete --build-dir=build-vc12-x86 -sBZIP2_SOURCE=E:\workspace\deps\bzip2\src -sBZIP2_BINARY=bzip2 -sBZIP2_INCLUDE=E:\workspace\deps\bzip2\install\include -sBZIP2_LIBPATH=E:\workspace\deps\bzip2\install\lib\Release -sZLIB_SOURCE=E:\workspace\deps\zlib\src -sZLIB_BINARY=zlib -sZLIB_INCLUDE=E:\workspace\deps\zlib\install\include -sZLIB_LIBPATH=E:\workspace\deps\zlib\install\lib architecture=x86 address-model=32 stage --stagedir=E:\workspace\install
}}}

The result is:

I can build boost by removing ''using mpi'' or ''using python''.

using python: OK

using mpi: OK

using python + using mpi: error
