Can you start from the commandline and post the output or create a log file (parameter -l)?

Sure, I've added the output

------------------ CRASH 1 -------------------------
In this crash, the program became unresponsive for a second or so and then seg faulted. I did a few random moves and rotates. Then clicked OK.

----------------- CRASH 2 -----------------------
In this crash, the program immediately disappeared with a seg fault (no period of unresponsiveness). I did a few random moves and rotates (most likely not the same as the ones in CRASH1).

Re: Full crash when trying to transform simple body

Post by bobmel »

One final crash output:

----------------- CRASH 5 -----------------------

In this crash, which took me longer (more moves/rotates) to trigger, the program immediately disappeared with a seg fault (no period of unresponsiveness). I again did a few random moves and rotates (not the same as the ones above).

Could you please edit your previous posts and put the output in code tags? That makes it easier for the developers to look at.

Re: Full crash when trying to transform simple body

Post by bobmel »

I think I've now identified a movement and rotate pattern which consistently causes a seg fault on my setup.

1. Click on Green Arrow.
2. Translate in direction opposite to GREEN Arrow.
3. Click on Red Sphere.
4. Try to rotate in direction opposite to Green Arrow (counter clock-wise).
The Transform object disappears and only the rectangle object remains (highlighted).
5. Click 'OK' (on Transform dialog).
6. Move mouse. (This seems to be needed)
[ CRASH - SEGMENTATION FAULT]

The output shows the following:

Coin warning in SbMatrix::inverse(): Matrix is singular.

The actual question is why you get this flood of singular matrix errors. I assume that this is somehow related to the crash.

I didn't get a crash, but I did get all the coin warnings in the console. I think it is this all over again.https://forum.freecadweb.org/viewtopic. ... =10&t=1381

I saved the core dump files for the last two crashes and can upload them if that would help.

In theory I could also make the VM available but the problem is that the VM disk is 62 GB.
