I think that's your problem right there. You should not need to do
that, and doing so will likely result in having multiple copies of the
DLL in your process (you can confirm with process dependency walker).
This should be avoided at all cost, as the python C API is not
designed to deal with this, and your crashes are pretty typical of
what happens in those cases.
