Description pitamila 2012-11-28 22:35:35 UTC 
Hi,

I use debian unstable with:
Gallium 0.4 on AMD RV770 and libgl1-mesa-glx 8.0.5 and libtxc-dxtn-s2tc0 Version: 0~git20110809-3

When I launch etqw demo I get this backtrace in gdb:
Program received signal SIGSEGV, Segmentation fault.
0xblahh in rgb565_image () from /usr/lib/i386-linux-gnu/libtxc_dxtn.so
(gdb) bt
#0 0xblahhh in rgb565_image () from /usr/lib/i386-linux-gnu/libtxc_dxtn.so
#1 0xblahhh in tx_compress_dxtn () from /usr/lib/i386-linux-gnu/libtxc_dxtn.so
#2 0xblahhh in ?? () from /usr/lib/i386-linux-gnu/dri/r600_dri.so
#3 ...
.
.
.
(gdb)

I saw on https://github.com/divVerent/s2tc/issues/1 I will try quake4
later to see if it could be the same bug. Does somebody maintain this
alternative s3tc lib? I hope this is a usefull place to report this bug

thx for support and at your disposal for further testing
