@lebedev.ri Thanks, will add a test. Besides, the bug fixed in ea7ab5a42cd4 seems to have the same root cause.

@kuhar @lebedev.ri I'm lucky to have a test case which requires exactly 1001 times iteration thus aborts. And would it be better just break out rather than report a fatal error?

Yes, there're similar cases our team have found related to data dependence that may prohibit interchange. And I'd like to spend more time to see if there's a sophisticated solution.
