Some work has been done to improve reproducibility in ITK, so it makes sense to try [ITK 5.0 beta 3](https://discourse.itk.org/t/itk-5-0-beta-3-github/1504) which is the most recent pre-release. If the problem is still not deterministic, that would be a bug in either library or your code. If it is deterministic, it will allow you to set conditional breakpoints based on frame index etc allowing easier debugging.
