FYI: I have kicked off different test jobs and am running different fuzzers over the weekend. I am testing this with interchange enabled, the cache line set to 64, and have disable the cost model, to test interchange as much as possible as suggested. I have already found one unrelated issue, #133922, but will report back next week on the interchange results.
