I tried capturing mir just before the live intervals before regalloc, which is the one where it fell over, and running from there, but it did not reproduce the failure. I think it is too sensitive to what order it sees the MOs when iterating, which would be potentially different between reading a mir file and getting real output from earlier passes.
