Thanks much for this testing.
Could you send the entire build log again. Perhaps there is something
I've made a fix which should work better on 64-bit.
More 64-bit testing needed.
One trick to test the buffered section of code using smaller arrays is
to set the buffer size to something very small (but a multiple of 16 ---
16 is the smallest). For arrays smaller than the buffer size, array's
are just copied when a cast is needed. But, for larger arrays, the
buffered code is exercised.
At some-point we might play with different buffer sizes to see if some
numbers are better than others.
