Summary0002200: Application crash when modifying fillet
DescriptionApplication crashes when changed affected edges on a cut of two cylinders.

When doing a boolean-subtract to cut a thin cylinder through a bigger cylinder sideways, the round end of the cut becomes a set of 4 curved edges.

Making a fillet for this set of four works, removing some crashes the Application.
Steps To ReproduceSteps 1-5 already done in file attached. But also reproduces every time when clicking a new model.

1. Make Cylinder, 10mm tall, 2mm radius, move to 0/0/-5mm.
2. Make Cylinder, 10mm tall, 1mm radius, move to -5mm/0/0, rotate 90deg around (0/1/0)
 ( they should intersect at their centers now )
3. Create boolean-diff, subtracting the thin from the thick.
4. Select the four parts of edge on one end of the cut-through hole.
5. Add a fillet with 0.2mm radius.

(or load the file attached and start @ 6)

6. Double-click 'Fillet' in Hierarchy, deselect last of 4 edges in fillet.
7. Click OK. Nothing changes in object in view.
8. Double-click 'Fillet' in Hierarchy, deselect last of 3 edges in fillet.
9. Application crashes immediately when clicking on the check.
TagsNo tags attached.

It doesn't crash for me with current master code... But the fillet indeed cannot be executed for several combinations of edges... I suppose this is a limitation of OpenCasCade, not sure we can do much about it...

I can confirm this crash. However, it happens when de-selecting the last of the four edges. It's caused by a recursive call of SelectionSingleton::rmvSelection() which corrupts the internal iterator variable.
