After output was this error message:

*********************************WARN_ONCE*********************************
File radeon_swtcl.c function r100_swtcl_flush line 325
Rendering was 10 commands larger than predicted size. We might overflow  command buffer.
***************************************************************************
drmRadeonCmdBuffer: -22. Kernel failed to parse or rejected command stream. See dmesg for more info.

Then I tried to compile it. Compilation was successful but when I tried to run, there was same error. I  have Intel Pentium III 1.2 GHz, 512 MB RAM. My OpenGL is OK. Can you fix this problem?
