DIED. FAILED test 2
        Failed 1/8 tests, 87.50% okay

I surmise that there is something which set up
interpreter->has_early_DOD_PMCs = 1
before the test runs. So sweep 0 always triggers a DOD run. It needs sweep 1
or even
sweep 0 to be placed before sweep 0 in order to get
interpreter->has_early_DOD_PMCs == 0.
I've attached a fixed version of the test in case of my guess is correct.
