Do you think this "debug assertion" is happening in Boost.Python code
somewhere? I assume it's somewhere in the code you are wrapping.
I also can't help but notice that your C functions seem to take arrays,
not pointers to scalar values, and that leaves me rather confused as to
what type of Python object you could be taking as input and converting
into an array.
