Hi Sascha
Do you know if you're using an in-memory or on-disk phrase table?
I had a quick look at the code, and it looks like the in-memory phrase table
does not set the source phrase correctly, maybe the on-disk table has the
same problem.
A possible fix would be to implement a copy constructor for TargetPhrase,
which makes a deep copy, including its embedded source Phrase. I'd have to do
a bit more investigation to see if this fix would work, as I'm not so
familiar with this part of the code.
hope that helps - best regards - Barry
