When i try to launch a map in ut2004 i have a crash durring the loading (or
just at the end of loading)

If I haven't debbuggeur attach ut2004 terminate on a DBUS error (Signal SIGBUS)

If I add a sprintf before memcpy in r600_upload.c I was able to debug in
r600_upload_buffer.

The call stack was :

#0  memcpy() at ../sysdeps/x86_64/memcpy.S:267
#1  fprintf() at /usr/include/bits/string3.h:52
#2  r600_upload_buffer() at r600_upload.c:109
#3  r600_upload_user_buffers() at r600_buffer.c:239
#4  evergreen_vertex_buffer_update() at evergreen_state.c:1372
#5  st_draw_vbo() at state_tracker/st_draw.c:712
...
