libgl1_mesa_dri segmentation fault in _mesa_get_teximage

Bug Description

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 ?? ()
#1 0xb6dfaf5f in _mesa_get_teximage () from /usr/lib/dri/unichrome_dri.so
#2 0xb6deedbe in _mesa_GetTexImage () from /usr/lib/dri/unichrome_dri.so
#3 0xb7e3c456 in glGetTexImage () from /usr/lib/libGL.so.1

#8 0x08119897 in StelApp::init (this=0xbfb5ccb4) at StelApp.cpp:271
#9 0x0811a91a in StelApp (this=0xbfb5ccb4, CDIR=@0x83d6c34, LDIR=@0x83d6c38,
DATA_ROOT=@0x83d6c3c) at StelApp.cpp:74
#10 0x080f23c6 in main (argc=Cannot access memory at address 0x0
) at main.cpp:247

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)

Thanks for your bug report. Does this still happen in Gutsy or Hardy? If so, please attach your Xorg.0.log and xorg.conf.

I upgraded to Hardy last night and the Unichrome driver is working much better for me now. The machine will still lock up ocasionally but glxinfo no longer segfaults. If I naorrow it down further I'll attach a backtrace.

Good work!
