Client crashes frequently on ubuntu

[bcmpinc]

I'm running the client under ubuntu 11.04 and it crashes quite frequently. The crashes happen totally at random. I believe it has something to do with reading/writing past array boundaries. I'm using the debian package of the client, but it is not specific for that version, as it also happens with a local build of a recent checkout of the repository and with minetest-delta (which uses a rather old code base).

I've executed minetest in both gdb and valgrind. The back-trace of gdb says that the segmentation fault occurs below `map.cpp:5878:driver->drawMeshBuffer(buf);`. Valgrind tells there are frequent uses of uninitialized memory. These might be in irrlicht or in other libraries, they might also be in minetest itself. Valgrind finds about 10 million errors in about 5 minutes.

This is my OpenGL driver info:

Code: Select all

Using renderer: OpenGL 2.1
Gallium 0.4 on ATI RV515: X.Org R300 Project
OpenGL driver version is 1.2 or better.
GLSL version: 1.2

I was wondering if other people have the same issue.

[Tafelpoot]

I got random crashes as well (every 0 sec - 20 min) on Ubuntu 11.04, a Gnome desktop, and the error is segmentation fault.

I have the same graphic card and the lastest mesa drivers

Code: Select all

OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RV515
OpenGL version string: 2.1 Mesa 7.10.2
OpenGL shading language version string: 1.20

I compiled the latest builds in the repository.

debug.txt is empty because of the crash. Crashes happen often when mining in open air, but I think it's related with the corrupted data issue on the windows versions.
Any fixes out yet?

[No-Half-Measures]

Please post at least the last 20 lines from your Debug file.

Crashes do not wipe the Debug.txt as the game only Writes to file does not delete lines.

Install Minetest From PPA and then download minetest.tar.gz and compile it.See if there is any difference.Also Tell us more about your computer.Do you have nvidia driver install on your system?

[Tafelpoot]

The graphic card is an ATI X1300, this is called ATI RV515 in the driver. So no nvidia.

But it often stops at just the digging as well.

Segmentation fault

Seems like a World related issue not seen it before though, Have you tried deleting your world folder and then starting again seeing if the problem still occurs?

Edit:

or it could be the below since its a Segmentation fault.

Access violation is the Windows counterpart of segmentation fault.

But that is not the original problem, it is just caused by bad error handling - the actual problem is "Unsupported texture format", but I can't really say much about that.

It's probably some problem either caused by OpenGL on your computer not accepting some dynamic textures made by the game or Irrlicht being somehow incompatible with your OpenGL.

I suggest trying to use direct3d9 as the graphics backend, by appending "video_driver = direct3d9" to the configuration file minetest.conf.

See http://celeron.55.lt/~celeron55/minetes ... ation_file

Though im not sure im just going by Cel mentioning segmentation fault in the quote.

[celeron55]

I've executed minetest in both gdb and valgrind. The back-trace of gdb says that the segmentation fault occurs below `map.cpp:5878:driver->drawMeshBuffer(buf);`. Valgrind tells there are frequent uses of uninitialized memory. These might be in irrlicht or in other libraries, they might also be in minetest itself. Valgrind finds about 10 million errors in about 5 minutes.

Can you provide the full valgrind log and the gdb log with backtrace (for every thread) of the debug build?

[Tafelpoot]

I'm not that experienced at this, so you might have to explain a bit how to do all this.

I ran

Code: Select all

$ gdb ./minetest
(gdb) run

which gave me this :

Good to know that it is not a bug in my system.

I've created a patch that works around the bug. It is an ugly hack, but at least you can keep playing. I've also put it on github so you can cherry-pick it if you like: https://github.com/bcmpinc/minetest-delta

[Tafelpoot]

do you mind explaining how to install this ? thank you !

[bcmpinc]

Do you know how to compile minetest? Or any other c++ program? If not, you need to install a few dependencies first. Open a terminal and enter:

Code: Select all

sudo apt-get install build-essential libirrlicht-dev cmake libbz2-dev libpng12-dev libjpeg8-dev libxxf86vm-dev libgl1-mesa-dev git

You can then clone my minetest-delta fork using:

Code: Select all

git clone git@github.com:bcmpinc/minetest-delta.git

Then you can compile it using

Code: Select all

cd minetest-delta
cmake . -DRUN_IN_PLACE=1
make -j2

And if everything went right, you can then run it with

Code: Select all

cd bin
./minetest-delta

[bcmpinc]

Here a backtrace with debugging symbols. I know it is not vanilla minetest, though with every other build I've had I encountered this bug. I'm not sure if this is a minetest bug, as it might as well be a bug in irrlicht or the 3d driver (whose first release is about half a year ago).

Thank you very much !
I did compile it myself, but I just followed the instructions on the site
No more crashes woohoow

[celeron55]

I'm not sure if this is a minetest bug, as it might as well be a bug in irrlicht or the 3d driver (whose first release is about half a year ago)

You are right in that it might be a bug in Irrlicht, or even in your graphics driver. It probably should be reported to the Irrlicht devs at least.
