Pcbnew crashes on drag in GAL canvas

[Karl Zeilhofer]

I was not able to track down the exact action, when pcbnew crashes. It is not really reproduceable.
But it allways happend, when i wanted to drag vias or traces with the shortcut 'G'.
I recorded a video, which you can see here: https://youtu.be/wCsSayC-kGY

Hi Karl,

I am getting "This video is private. If the owner of this video has granted you access, please sign in."
Is is specific to a board or happens with any file?

Orson

[Karl Zeilhofer (zeilhofer)]

Hi Orson,

excuese me, i set the wrong permission. I didn't want it to be pulic (it could be understood as bad news). Now it is "not listed". You should be able to view it now.

I did not try it with another board. Don't have the time now.
It seemed to me, that it only happens, when you are working rather fast - could this be?

kind regards,
Karl

[Maciej Suminski (orsonmmz)]

That is no problem. Thanks for recording the video, it always eases the process of reproducing a bug.
Aside from the problem, I am wondering - why do you press 'W'? Is it the hot key responsible for the Push and Shove router activation? If so, did you remap it or was it like that since the beginning?

We need to find a way to reproduce the bug or gather some more information:
1) Could you send us the .kicad_pcb file that exposes the bug? I would simply try to follow steps shown on the video.
2) Do you build the debug version? If so, running KiCad under gdb will allow you to obtain the backtrace that is a great help in debugging.

Regards,
Orson

[Maciej Suminski (orsonmmz)]

I have just noticed that you are using revision 5054. Since that time there were a few bugfixes to both OpenGL canvas and Push and Shove router, so there is a chance that the issue is already solved.

Orson

[Karl Zeilhofer (zeilhofer)]

The Short cut 'W' is for adding trace.
you can see it in the video, that the corresponding toolbutton gets pressed.

I remaped some commands.
here my list of shortcuts (copied from the menu Preferences -> Hotkeys -> List current Hotkeys):
I have to admit, that the shortcuts 1,2,3,4 (switching between layers) do not work. I don't knwo why.

I am a bit surprised, as W in my case changes the width of a track in the Push and Shove router mode. This might be an indicator of a separate bug. Could you tell me which keyboard layout do you use?
Currently, hot keys remapping using the hot key editor does not work in GAL mode, therefore the only way to change it is to edit the source code.

[Karl Zeilhofer (zeilhofer)]

I'm using the german-austria keyboard-layout.
very strange. somehow this special remap did work for me. but as said before, other shortcut changes didn't work correctly.

[Maciej Suminski (orsonmmz)]

Hi Karl,

Did you try a newer revision of KiCad? It is really important to know if I should spend time trying to reproduce the bug or work on something else. For the time being, I assume it is fixed, unless someone else confirms it in a newer version.

Regards,
Orson

[ro0ter (dorin-chira)]

hi everybody,

i would like to subscribe to this problem. Worse than this, kicad pcbnew actually malformed the kicad_pcb file.

how can i confirm this bug? how can i help you to reproduce it? how can i participate to fix it?

it is very annoying and I can hardly refrain myself from using bad words... besides the fact that it does not have a very well developed component library, it does screw your work from time to time... this is very bad, but I would like to help this software grow.

kindest regards,
ro0ter

[Maciej Suminski (orsonmmz)]

Hi ro0ter,

To fix a problem, we need to find a way to recreate it. If you have any hints how to do it, please tell us. What revision & platform do you use? Please copy the version string from Help menu and paste it here.
Is it possible to get the malformed file? I may try to recover it and at the same time look for traces that could point out the problem.

Regards,
Orson

[ro0ter (dorin-chira)]

Hello Orson,

Thank you kindly for your quick answer. I have removed the entire project whose pcb I have lost, that`s a 2-hours work. Anyway, as they say, each subsequent version is better and better.

Regarding the crash - I can reproduce that very easily:
OS: Win7 En x64 SP1 inside vmWare Player, 2GB ram
Kicad: build 2014-12-04 BZR 5312 with wxWidgets 3.0.0u, boost C++ (running under wow)

Steps to reproducec:
1. please load the project "some isp adapter"
2. open the pcbnew editor
3. switch to DirectX (press F11)
4. enter trace drawing mode (press x)
5. enter trace dragging (not moving) mode (press g)
6. try to drag any contour trace. ==> CRASH

I can reproduce it over and over again, Should you need assistance, I can have a debug kicad run on my machine and gather the traces.

I really want to look more into kicad, but I do not have the time yet. I will seek ways of building and debugging it. I am a software engineer in industrial automation.

Regards,
ro0ter

[ro0ter (dorin-chira)]

Well... this is embarrassing... I don`t know how I did it, but here it is: two posts with the same thing. It seems the first one was posted before I named the uploaded file. Sorry for this...

An administrator - please remove first duplicate post and this one as well. It seems I can`t...

[Maciej Suminski (orsonmmz)]

The attached file is indeed very helpful - now I am able to reproduce the problem and investigate it further. Thank you!
Do not worry about the double posting, it simply happens from time to time.

Regards,
Orson

[Sven D (sven-d)]

The bug was automatically set to expired from Launchpad.

I can still reproduce the bug in revision 5561

[Benjamin Kohl (ben-819)]

I am using revision 5618 and it still crash frequently when moving vias with the G key and while the Interactive Router is enabled (Open GL).

Okay, this might be the same bug:

valgrind report attached to this one, might be helpful.
