Assembly crash #17144

Closed leventelist closed 2 weeks ago

leventelist commented 3 weeks ago

Is there an existing issue for this?

Problem description

When creating a distance joint, I get segfault.

Program received signal SIGSEGV, Segmentation fault.

leventelist commented 3 weeks ago

It seems that it is not Assembly specific. It crashes all the time.

maxwxyz commented 3 weeks ago

Please check out how to report issues which could help us diagnose and fix it.

leventelist commented 3 weeks ago

Further analyzing the issue, I discovered it is only present when there is a grounded object in the assembly.

leventelist commented 3 weeks ago

crash.zip Attached is the test case for the crash. I started to build everything from scratch, and it crashed after a while. To reproduce the issue, start adding more joints to the pushbuttons. Please use the assembly.FCStd for test.

luzpaz commented 3 weeks ago

@leventelist can you reproduce on latest dev ? (https://github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds)

leventelist commented 3 weeks ago

Here is some gdb trace...

assembly_new#Distance006 is unconnected to a grounded part so it is ignored.

@luzpaz I try it. Compiling the latest main.

leventelist commented 3 weeks ago

@luzpaz I can confirm, that the same issue happens with latest main. 1.0rc1-285-ga9bff78974

I cannot get it to crash. Can you record a macro or screencast of what you are doing? @PaddleStroke FYI

I falsely enable A2P, but when I select the assembly, the right WB is selected.

This is how I configure FreeCAD:

cmake ../ -DFREECAD_QT_VERSION:=5 -DBUILD_DESIGNER_PLUGIN:=ON -DPYTHON_EXECUTABLE=/usr/bin/python3

maxwxyz commented 3 weeks ago

could you try it with the weekly builds: https://github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds

leventelist commented 3 weeks ago

I tested it yesterday on this commit: 1.0rc1-285-ga9bff78974, and it still had that bug.

luzpaz commented 2 weeks ago

An aside, @leventelist can you put your backtraces in triple back-tick code blocks. This way you aren't triggering links to non-relevant tickets when you paste backtraces. TIA

PaddleStroke commented 2 weeks ago

I cannot reproduce the bug. However looking at the trace the problem seems to come fromAssemblyObject::isFaceType I think perhaps the problem came from the use of static_cast to Part::Feature .

Which is coincidentally fixed in the PR https://github.com/FreeCAD/FreeCAD/pull/17205 @leventelist can you try this PR and feedback if it still crashes? Alternatively if you can't build this PR can you try after this PR merges?

PaddleStroke commented 2 weeks ago

As a side note, when filling a bug report, could you please post a minimal example and clear reproduction steps? ie clear the document to remove as much as possible to keep only the minimum objects that trigger the problem. This way it is easier to reproduce and fix.

PaddleStroke commented 2 weeks ago

I have just tested your file again after building out of https://github.com/FreeCAD/FreeCAD/pull/17205, and opening the file and calling a solve of your assembly does crash freecad.

So it looks like this bug is fixed by https://github.com/FreeCAD/FreeCAD/pull/17205.
