[gdal-dev] gdalbuildvrt changes data when building VRT

I'm using gdalbuildvrt as a simple way to merge adjoining data files.
Unfortunately, I'm noticing that some values change.  I've created a
simple test case where I make a VRT from a single GeoTIFF and compare
histograms before and after, and I've attached it to this message.
Can someone tell me why this is happening and how to avoid it?
Thanks!

Jack.
