Well, I still can't find the magic to reproduce this myself, but our overnight
tester shows the failure
(http://gcc.gnu.org/ml/gcc-testresults/2013-05/msg00094.html).
Richi, this is another test that started failing with the same commit as
PR56865. In this case, it appears we are now vectorizing a loop that we
formerly expected not to. Are you able to reproduce this?
Andreas, would you be able to provide -fdump-tree-vect-details information for
r196871 and r196872 to make it easier to debug the problem?
Thanks,
Bill
