Summary0004129: Crash on setting certain dimensions in a sketch
Description- open the attached example file
- open the Sketch "Sketch-Pinpad"
- set for the Edge 2 a vertical constraint (e.g. 3mm)
- close the sketch

result: crash
One out of 5 times it does not crash and I get an "access violation" in the report view.

The crash could be reproduced also on Mac.

I have reported the bug upstream to OpenCascade and provided a patch for a possible solution. With the patch an exception is raised, which is catched by FreeCAD and the crash is avoided:

@kunda1
I think you do something with upstream reported OCCT tickets... so I let you do your magic ;)

@abdullah I've added this ticket and companion upstream tickets to the thread tracking upstream OCC bugs: https://forum.freecadweb.org/viewtopic.php?t=20264 ;)

There is no solution other than wait for OCCT to solve the access violation:

Until them, this ticket remains as acknowledged.
