Use pointer instead of unsafe_convert

[yuyichao]

This fixes the error due to the Base memory buffer change (the cconvert for Arrays returns MemoryRef now and the unsafe_convert takes in MemoryRef rather than Array accordingly).

Adding cconvert would also work but since the input type is know it's not necessary to do that.

Thanks for the PR! As far as I recall, I used unsafe_convert over pointer since the former seemed a bit faster. But now I see that one just calls another in this case, so perhaps I was mistaken.

A new version with this would be nice (if possible).

Sure; done.
