Anthony Molinaro commented on THRIFT-1321:
------------------------------------------
I see how that could be the case, but I'd like to reproduce this error with a
simple case, starting with a thrift definition and doing serialize/deserialize
(like in the snippet I included before). I used binary values in the snippet
and things seemed to work, so I'm still not certain how this manifests itself.
Do you have a test which shows the bug happening? Otherwise I can try to
figure out a way to reproduce it sometime soon.
