You may be interested to know that I eventually solved this problem. Our code was using GetNewAndDeleteFromCryptoPP, implementing our own version as per the Readme.txt file. But it wasn't working fully for us. I took at look at the cryptotest and saw that it was using SetNewAndDelete. I went and did likewise and now it is working. Hurrah!
