In MultiClassificationSVM::trainWithoutScaling there are parallel tasks spawned using Parallel.forEach . This restults in non-deterministic classification results. Serializing this fixes the problem.

The reason is that somehow the SVMs size is truncated and data is lost. My feeling is that the issue is within KernelQMatrix.
