--- Comment #9 from Vladimir Makarov <vmakarov at gcc dot gnu.org> --- Cycling is the worst what can happen to compiler (even crash is better). This is the highest priority PR right now for me. I can not say why the cycle does not finish. It should as it works only for reload pseudos. I'll investigate it more. In any case I hope to fix it on this week. Sorry for inconvenience.
