https://bugs.freedesktop.org/show_bug.cgi?id=33494 --- Comment #1 from XoD <xoddark@xxxxxxxxx> 2011-01-25 12:13:11 PST --- 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 ...
