Is there an existing issue for this?

  • I have searched the existing issues

Problem description

FreeCAD (on Linux) crashes randomly, i.e. without obvious pattern, when selecting edges or vertices for subsequent joining by a (in my case, probably irrelevant) fixed joint. I have now seen five(!) crashes within about two hours of work on a fairly simple assembly. If memory serves right, three of the five crashes where while working on a sub-assembly, the other on the main assembly (only involving part directly added to the main assembly, not involving any sub-assembly).

The file contains only two bodies, both referenced from a second file using a sub-shape binder. Several copies of each of the two bodies are added to the assembly using the toolbar icon to add parts, so these are added as links (if this is the right term, I am new to FreeCAD and its terminology).

I checked existing issues #18705, #17162 and #15202, but they seem to be different.
However, I am also affect by the #18044 problem: After the crash restarting FreeCAD produces many "Reading failed from embedded file: <some_file_name>.bin (0 bytes, 2 bytes compressed)" messages. Luckily, only the recovery file is corrupted in my case, and the manually saved files are still fine.

All crashes produced the same stack-trace in the console window where FreeCAD was started:

Short Update: Next crash, same stack-trace, this time selecting a face. The crash occurred right after the face turned dark green after clicking it. It was the second face selected, while holding Ctrl key pressed to add as second selected feature.

Sequence of actions was: Select a body in tree view. Zoom and rotate using mouse wheel and middle button to see its bottom face, select that face (left click, it turned light green). Zoom out a bit using mouse wheel. Point mouse to other nearby body in 3D view, zoom, pan and rotate with mouse wheel and middle button to see its top face. Left-click top face. Crash.

Note: 3D Navigation mode is set to "Blender".

Loading recovery on restart produced this additional error:

23:35:55  BinTools_ShapeSet::Read: File was not written with this version of the topology
23:35:55  Reading failed from embedded file: Box.SuppressedShape.bin (0 bytes, 2 bytes compressed)
