--- Comment #2 from David L. equinox-freedesktopbugs@diac24.net 2011-06-21 22:19:08 PDT --- i hacked up a counter to tell me which instruction is failing, it seems to be
2517: ADD TEMP[161].x, -TEMP[158].xxxx, CONST[0].wwww
if i'm not totally wrong. (my counter says 2518, but it is an ADD that fails so i think I'm off by one...)
