The following nightly tests on 05/05/28 failed the above assertion
on account of this bug:
gc.memory.FillingStation
gc.gctests.Compact.compact007
gc.gctests.Compact.compact008
gc.gctests.WeakReference.weak001
gc.gctests.Compact.compact015
gc.gctests.Compact.compact014
However, these tests have not failed on subsequent nights, even when testing
the same bits. This bug is thus a placeholder for further investigation
should the error recur in the future.
Here is a typical rerun.sh file for one of the tests:
