Hi,
When building ctypes (1.0.2-5) on amd64, I get the following error:

It seems that the "fn" in ffi_call() (#2) is what is getting called,
which that gets from _CallProc()'s pProc:
(gdb) frame 3

at source/callproc.c:668
668 ffi_call(&cif, (void *)pProc, resmem, avalues);

3362 result = _CallProc(pProc,
Which comes from:
