Slicer crashes on Show3D in SegmentEditor

Hello,

I’m using Slicer to segment single slices (not all) of a biological microCT sample. Unfortunately, after a while, I guess when the segmentation has reached a certain size, Slicer crashes with the error: “slicerApp-real.exe has stopped working”. I noticed that this error only occurs, if I have the segmented slices plotted in 3D. When I do the segmentation without having activated “show 3D” in Segment editor, I do not face this issue. Furthermore, if I later on try to activate “Show 3D”, slicer crashes immediately most of the times.

Also when I load the segmentation without a stack, slicer crashes upon “show 3D”. I faced this issue on two machines, both with the latest slicer version installed and quite a lot of RAM (64 GB), furthermore, I have another segmentation of that size, that also elicits the same behaviour. Therefore I suspect it is independent of the machine, probably dependent on the files, but these have been fully created in Slicer. The final segmentation (XYZ.seg.nrrd) is about 11 MB. It comprises a segmentation on about 50 of 2388 slices, so on average every 40th to 50th slice is labeled with 2 Segments. If it helps, I can send or upload one of the segmentations that cause the error.
In the following the log file of the session in which I loaded the segmentation and slicer crashed upon show3D in segment editor.

Many thanks for your work on slicer so far and thanks in advance for your help.

Please try the latest Slicer Preview Release has errors, too. If yes, then please share the segmentation file so that we can debug.

Installing and using the latest Preview release totally solved that issue. Thanks for your help! And sorry for bothering you with that. I could have tried that myself…
