pybind11 python37_d.dll access violation
Turns out that pybind11 undefines _DEBUG
which causes Py_DEBUG not to be defined as well,
so one must explicitly define it in VS Preprocessor tab in order to avoid crashes
because of the size difference between the structures on pybind11 and python36_d sides.
