Is that definitely the right place? And is doing it only for small arrays going to be enough? Currently, PyCStructUnionType_update_stgdict does dict = PyType_stgdict(desc); and then stgdict->ffi_type_pointer.elements[ffi_ofs + i] = &dict->ffi_type_pointer; where dict is the ctypes object for the field type. If the ffi_type_pointer is used all over the place because arrays usually degenerate to pointers, and changing it would cause breakage elsewhere, maybe the answer is to have a new ffi_type_array field which is NULL for non-array types and set correctly for array types; then the above code can check for a non-NULL ffi_type_array and use that instead of the ffi_type_pointer? Or am I talking nonsense? Oddly (or perhaps not), this failure doesn't seem to occur on Windows - no crash happens and the correct value is returned from a function which sums the array, as in this example.
