[gdal-dev] Problem using RasterIO to flip image

I am trying to write an image that has a y inverted buffer.

I tried this:
band->RasterIO(GF_Write, x, y, width, height, data + width * (height - 1) *
width, height, GDT_Int16, sizeof(short), -width * sizeof(short));

But I get a segfault in memcpy.

What am I doing wrong?
