pcbnew DRC crashes after importing HydraBus 1.0 Rev1.3

[Benjamin]

The project HydraBus with eagle files required for this issue is open hardware and available on github in following link:
https://github.com/hydrabus/hydrabus/tree/master/hardware/HydraBus_1_0_Rev1_3

When we import this project with KiCad 6.0 nightly of even KiCad 5.0x there is different issues
So let's do it step by step with KiCad nightly kicad-r11991-11Dec2018 (http://downloads.kicad-pcb.org/windows/nightly/kicad-r11991.9490fd9d3-x86_64.exe)
1) git clone https://github.com/hydrabus/hydrabus.git to hydrabus_git

2) Launch KiCad and Import Eagle Project Files => Choose hydrabus_git\hardware\HydraBus_1_0_Rev1_3\HydraBus_1_0_Rev1_3.brd

3) Choose project destination (create directory HydraBus_1_0_Rev1_3_Kicad) => hydrabus_git\hardware\HydraBus_1_0_Rev1_3_Kicad
kicad Information open with lot of warning about tKeepout(39) which is converted to Dwgs.User layer
As KiCad does not support KeepOut it is OK and it is minor issue
so click on OK
Now the board is displayed correctly so save it

4) If we do "Perform design rule check", KiCad crash with a window kicad.exe has stopped working

5) We restart KiCad and we do again "Perform design rule check" no there is no any crash.

@Benjaman, please include the kicad version information. I just tested this using the development branch of kicad and the DRC crash does not happen.

The fully enclosed polygon is most likely a bug in the board layout. KiCad expects the polygon that defines the board outline to be fully enclosed. This most likely indicates that the line end points that define the board outline in eagle are not enclosed due to small gaps.

AFAIK, graphic image import from eagles schematics is not supported.

I do see the dashed crossed line in the schematic. I'm not sure why they are there. Does eagle support hidden lines? If so that could be an issue because kicad does not support hidden lines.

For future reference, please do not file multiple bugs in a single report. It is not possible to close part of a bug report in launchpad.

I confirm i retried again and the crash does not appears
So it seems hard to reproduce

[Benjamin (bvernoux)]

In fact after a second try with 3D Viewer kept open and go to PCbnew => Perform design rule check it crash

[Benjamin (bvernoux)]

I have catched the crash with Visual Studio 2013 but as it is a release there is no debug symbol
Unhandled exception at 0x0000000013B80178 (_pcbnew.kiface) in kicad.exe: 0xC00000FD: Stack overflow (parameters: 0x0000000000000001, 0x0000000000033F80).

I can provide a dump if you want but I think the best will be to try with a debug version
I'm waiting your feedback

[Wayne Stambaugh (stambaughw)]

Even with the 3D view open, I still do not get a crash on DRC. I just
get a DRC warning about the fully enclosed board outline.

After lot of retry from scratch, removing the directory HydraBus_1_0_Rev1_3_Kicad and doing step 1) to 5) I cannot reproduce it (so far I have reproduced it only 3 times with at least 50 tries...
So we can say it is a pseudo random crash / very hard to reproduce bug
The most important is to know how to fix this polygon not enclosed with wrong coordinate 0.00 ...
?
Maybe it is linked to the fact the Edge.Cuts is part of a footprint U$1 ?
Also the Edge.Cuts line thickness is 0 so it is very hard to select it...
