Segmentation fault while manual routing in OpenGL

[Xavier]

Kicad crashed after a while when interactive routing. You've been saying you can't reproduce this bug, but what can I do? I sent you before the GDB output and the board I was working on. This is other small design. Crashes happen in my laptop and my desktop, both 64b.

Hi Xavier,

I apologize if you read my response to the previous report as harsh, I did not mean it. I just wanted to know if there are any hints that could help us triggering the bug, as sometimes it is enough to perform a specific action to diagnose a bug. Apparently here we have a bug of tough kind, so it may take some time before fixing it, unless we find a reliable way to reproduce it.

Regards,
Orson

[Maciej Suminski (orsonmmz)]

I have just committed a patch from Tom that can potentially fix the problem (revision 6043), so please let us know if the problem persists afterwards.

Regards,
Orson

[Nick Østergaard (nickoe)]

Marking critical beacuase it is a crash.

[Xavier (fjrg76-z)]

Hi Orson,

I'll install the latest update ASAP, and I'll let you know the outcome.

Thanks!

Hi Orson,

For some strange reason I've experiencing segmentation faults whenever I try OpenGL mode. In fact, I've saved some GDB outputs besides the one I posted. If you're interested I can sent them to you.

And no worry, we're Ok, and thanks for your great effort in Kicad.

Regards!

Hi Xavier,

Please send me the reports. Does it happen both with a board loaded and without?

Regards,
Orson

[Xavier (fjrg76-z)]

Hi Orson,

I'm sending you part of the report. Same day two runnings in a row.

[Maciej Suminski (orsonmmz)]

Hi Xavier,

I need some more clarification here. I guess it might be better to move it to another bug report, as it seems to be a different problem than the one related to the router.

According to what I see in the backtrace, I am guessing you are using the legacy canvas to remove tracks by selecting an area and trying to remove the selection? It does not crash directly after switching to the OpenGL canvas (as I have understood from the previous message)?

Regards,
Orson

[Maciej Suminski (orsonmmz)]

Xavier,

Has the segfault described in the report happened when you were working in GAL or legacy canvas? It seems to me that it was caused by removing a track in the legacy canvas.

Does pcbnew really crash right after switching to OpenGL without any preceding actions in the legacy canvas?

What is the problematic revision number?

Regards,
Orson

[Maciej Suminski (orsonmmz)]

Hi Xavier,

Any comments on the above questions?

Regards,
Orson

[Maciej Suminski (orsonmmz)]

Hi Xavier,

Tom has recently pushed a few fixes to the Push and Shove router, could you confim the problem still ocurrs? It still not clear to me whether there is another issue that you have shown in the attached backtraces. If so, would you give us a hint how to reproduce it?

Regards,
Orson

[Xavier (fjrg76-z)]

Hi Orson,

I'll try my Kicad design routine so that I can reproduce the bug, it it still exists.

Thanks!

[Strntydog (strntydog)]

I tried manually routing in OpenGL canvas Yesterday, using the latest Kicad from the daily PPA. It was segfault like this, every few tracks. I edited manually. I had to switch back to Default Canvas, which doesn't crash. Most of my tracks were routed on the Default canvas, and i was trying to use the OpenGL canvas feature of pushing tracks to fix some clearance problems. Editing those tracks with clearance problems would randomly cause Kicad to lockup and then segfault.

[Nick Østergaard (nickoe)]

@Strntydog, could you provide the exact version information and ubuntu version?

Also, are you able to describe a way to reproduce this easily? Is it on an old board you are working on, or is it a fresh design?
