Bug#720385: minetest: game crashes with floating point exception

Wed Aug 21 18:21:24 UTC 2013

Hello.

> it seems to me that you don't have any OpenGL available, right?
I'm successfully run any other games; for example I launch minetest v
0.4.7 downloaded from git (branch stable-0.4) and compiled on my
computer:

ruslan at debian:~$ /home/ruslan/minetest-0.4.7/bin/minetest
Irrlicht Engine version 1.7.3
Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64
Using renderer: OpenGL 2.1.2
GeForce 6800 XT/PCIe/SSE2: NVIDIA Corporation
OpenGL driver version is 1.2 or better.
GLSL version: 1.2
Loaded texture: /home/ruslan/minetest-0.4.7/textures/base/pack/menu_header.png
Loaded texture: /home/ruslan/minetest-0.4.7/games/minetest_game/menu/header.png
Quit message received.

Now I'm launch minetest from Debian Sid:
ruslan at debian:~$ gdb minetest
