Public bug reported:
Binary package hint: libgl1-mesa-dri
Hi!
I got a segmentation fault during start of the stellarium program.
I reproduced the same bug (same function, same moment) with the SVN last
version of this program. The segmentation fault occurs inside the mesa dri
library.
NOTE: The bug doesn't occur when I use the vesa driver with my xserver
x.org .
Here is the backtrace:
#0 0x00000000 in ?? ()

If I put a breakpoint at the entry point of the _mesa_get_teximage function, I
get
the segmentation fault at the following step of execution:
Breakpoint 2, 0xb6e72d78 in _mesa_get_teximage ()
from /usr/lib/dri/unichrome_dri.so
(gdb) step
Single stepping until exit from function _mesa_get_teximage,
which has no line number information.
Program received signal SIGSEGV, Segmentation fault.
0x00000000 in ?? ()
My current config is:
Ubuntu 6.10
graphic card VIA KM400 with the last version of the ubuntu driver
(xorg-video-via 1.0.2.1)
libgl1-mesa-dri 6.5.1~20060817 (last version)
