[trunk] Add a temporary work around for issue 293

As described in the bug report the default allocation mecanism for codeblock data is too small for those dataset (16bits). We would need a finer (more granular) mecanism to reallocated only on demand. For now this help the two failing tests to pass.
Fixes issue 293
