> Running the attached test program against a cassandra 2.1 server results in scrambled
data returned by the SELECT statement. Running it against latest stable works fine.
> Attached:
> * Program that reproduces the failure
> * Example output files from mentioned test-program with the scrambled output.
> Failure mode:
> The value returned by 'get' is scrambled, the size is correct but some bytes have shifted
locations in the returned buffer.
> Cluster info:
> For the test we set up a single cassandra node using the stock configuration file.
