…ault 985b5d7 imported a patch that fixed one IngestExternalFile segfault, but it appears there is another. Import "Fix TSAN: avoid arena mode with range deletions" [0], which seems to the trick. This patch has landed on master but is not in 5.5.1. [0]: facebook/rocksdb#2399 Fixes cockroachdb#16922.

Summary: The range deletion meta-block iterators weren't getting cleaned up properly since they don't support arena allocation. I didn't implement arena support since, in the general case, each iterator is used only once and separately from all other iterators, so there should be no benefit to data locality. Anyways, this diff fixes up facebook#2370 by treating range deletion iterators as non-arena-allocated. Closes facebook#2399 Differential Revision: D5171119 Pulled By: ajkr fbshipit-source-id: bef6f5c4c5905a124f4993945aed4bd86e2807d8
