Steps to reproduce

  • Open the attached file Crash.zip
  • Edit the last Sketch006
  • Select the topmost Edge12 line.
  • Add h-length constrain for instance by pressing x

image

FC crashes with SIGSEGV.

Note changing a small thing like visibility of the SleeveScrew part or doing small edits prevents the crash or make it happend later. Sometimes it takes multiple tries to reproduce.

I can't seem to produce the problem. Do you mean by h-length the Horizontal Distance constraint? It's default shortcut is L. Could you please post your configuration here? Tools -> Edit parameters -> Export.

Indeed. I forgot I've changed the shortcut.

Turned out this is actually more tricky to reproduce then I first thought. Today I found out it depends on the main window size and won't crash if the window is too small. At least of my setup:

1

Edit: Seems it is not much about the size. But if I change the size and then reload the file (or freshly start the app and open it) and then add the constraint in a short time it usually crashes. Also I've collapsed the Constraints panel on the left size. But can't say for sure if it is related.

I've managed to reproduce SegFault with the same stacktrace, but using a different file. So it is not related to anything specific to the file.

From what I remember, I was in the Sketcher and trying to make the Constrains view in the Tasks tab display associated constraints (which I failed to achieve). Then did some small changes in the sketch. And then I think I used undo and it crashed.
