MSVC 14.0: Missing Symbols in Numpy Debug Library

Hi,

I'm having trouble with my debug build of Boost.Numpy. Everything works fine linking against the release version, but in debug mode, I get the following errors:

I copied libboost_numpy3-vc140-mt-gd-1_65.lib to boost_numpy3-vc140-mt-gd-1_65.lib previously so that the library can be found in the first place.

I built Boost using

b2.exe install link=static threading=multi toolset=msvc-14.0 address-model=64 --debug-configuration -j 4

I tried both

using python : 3.6 ;
using python : 3.6 : python
: # includes
: # libs
: on ;

and just

using python : 3.6 ;

in user-config.jam. Both lead to a functioning release library, but the same problem with the debug-version persists.

The same problem occurs whether building 1.64.0 patched from #125 or using the current snapshot from https://dl.bintray.com/boostorg/develop/.

Thanks a lot for your help!
