--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
A "p *info" would be useful. I can't spot a way for the info->cache to become
invalid, so that opens up the field to memory corruption. If you could install
valgrind and recompile with --enable-debug that may catch an assertion earlier.
If you could run X under valgrind and see if that flags the error, most useful.
