append second board ends in crash

I cannot duplicate this bug in either the legacy or opengl canvases. I
opened your control_board.kicad_pcb and then appended
monster_mkii_nutzen.kicad_pcb, power_bridge.kicad_pcb, and
signal_distribution.kicad_pcb in that order without any issues other
than it being really slow redrawing in the legacy canvas.

Ok, then try this:

- Open PCBnew standalone
- click append Board
- choose the attached board

for me it ends in a crash.

Still no issue either opengl or legacy canvases. Does the first board
opened make a difference before the append?

No the first opened board before the append makes no difference. On my PC i can reproduce the issue just with opening PCBnew without KiCAD. PCBnew has than opend an unsaved board design (just the frame is showed) and when i then append the power_bridge.kicad_pcb it crashes. But the strange thing is, if i do the same but append the control_board.kicad_pcb it works. So it seems to be something weird with the power board file.

Is there any log i can attach from my machine? Does KiCAD log events in some file at all?

This does indeed crash the current 4 stable branch in when using either
gal canvas. The legacy canvas does not have this issue.

It seems like it might be related to a gal canvas issue. But now that
we have a file that makes it crash every time, it should be easier to fix.

Thanks for the offer. Now that we can reliably reproduce the issue, we
should be able to figure it out.

Thanks
