It works with my tree (that has one ipa-icf fix I am about to commit today). As disucssed earlier, cycles in estimate_calls_size_and_time should not happen, because the function walks inline tree that can not have loops. So the bug is earlier. I would suspect that ipa-icf may make mess of aliases causing this to happen (that should be caught by the verifier but perhaps it isn't)
