The addr_mutable object supports overlapping insertion, but with insertion-order specific results. So, by changing the number of worker threads, we change the number of shard= s, and consequently the CUs indexed by each shard, and consequently the sequen= ce of insertions into each per-shard address map. This is fine for the non-overlapping cases, we'd expect the same collection= of pairs, just distributed differently over the shards. But for the overlapping case, that doesn't work. --=20 You are receiving this mail because: You are on the CC list for the bug.=
