I get a SIGTRAP on the demos which looks much the same with r600g and swrastg.

In case I am doing something lame/different here is my autogen -

./autogen.sh --prefix=/mypath --enable-debug --disable-egl
--with-state-trackers=dri  --enable-gallium-r600 --enable-gallium-swrast
--with-dri-drivers=r600,swrast


tgsi/tgsi_exec.c:1087:fetch_src_file_channel: Assertion `pos <
(sizeof(mach->Inputs)/sizeof((mach->Inputs)[0]))' failed.

Program received signal SIGTRAP, Trace/breakpoint trap.
