Yes, I understand's Peter's criticism now. Since I did not want to
post any company proprietary code I wrote a console app to demonstrate
the problem and lo and behold, it worked fine.

Turns out I was depending on some third party software to properly
store the byte array in a database and return it to me in its original
format. But they were not storing the very last byte. Their software
returned to me the correct number of bytes but the last byte was now
zero instead of the value I was expecting it to be.

Lesson learned: don't assume third party software is going to work as
you expect it to.
