I worked around this limitation by installing a 32-bit version of
Python. Unfortunately I don't understand enough of the bootstrapping

for b2.

Stefan,

I don't know about your personal case, however this is my boost-command-line that works with the 64bit python.
b2 toolset=msvc-14.0 address-model=64 variant=debug,release threading=multi link=static --with-date_time --with-thread --with-system --with-chrono --with-atomic --with-python --with-filesystem stage

Obviously I have other libraries built, and use visual studio 2013 - However this works for me. If you continue to have errors It may well be your python install at fault.
