      The attached reproducer consistently crashes the server.

      The order of operations is as follows:

      • A secondary begins initial sync and sets the timestamp for the oplog replay
      • Primary creates a collection collA
      • Primary creates an index on the empty collection collA (this creates a createIndexes oplog entry)
      • Primary inserts some documents into collA
      • Primary drops the index of collA
      • Primary begins creating the index again in collA (this is a two phase index build)
      • Secondary clones the collection with the in-progress index build and proceeds to also create the index
      • Secondary replays the oplog and crashes due to the in-progress index build
