In FilterSpecCompilerIndexPlannerWidthWithConditions.planRemainingNodesWithConditions, int sizeFactorized overflow to be negative.

1. Shall sizeFactorized be long?
2. Even if int sizeFactorized not overflowing, new CompermutationTriplets[sizeFactorized] sometimes went to OutOfMemory
3. What does this method do?
4. Not all my statements have the problem. What could be the cause? this is blocking our upgrade to 9.0.0 from 4.11. how to circumvent it?
