Segmentation violation when trying to run with AStar as main reconstruction algorithm

[AsaNehm]

When changing from TrackMethod = "Hough" to TrackMethod = "AStar" (Config/TMS_Default_Config.toml) the script ConvertToTMSTree fails right after the A* reconstruction before the looping over the Hough candidates.
