Comment 1 Jerome Glisse 2010-12-17 11:36:12 UTC

Created attachment 41220 [details] [review]
avoid segfault

Can you test if this patch helps

Comment 2 Öyvind Saether 2010-12-17 13:34:04 UTC

I applied patch 41220 and got the same SIGSEGV and backtrace. It did not help, but thank you for trying.

It's possible to run sdlmame games using r600g by turning vertex buffers off, add
gl_vbo 0
to
sdlmame/mame.ini

Comment 3 Jerome Glisse 2010-12-17 14:27:24 UTC

please do the following :
make clean
CFLAGS="-g3 -O0" ./autogen.sh --enable-debug --enable-gallium-r600
make -j3

And recapture the backtrace with this debug version. Use btfull and attach it here thanks

Comment 4 Chris 2010-12-17 14:56:15 UTC

I have this same issue, my bug report for it is here...

https://bugs.freedesktop.org/show_bug.cgi?id=32455

I have a full backtrace of the issue with a mesa debug compile
