Description
Ties
datavariable to lifetime ofIndexWrapperby making it struct member as opposed to local constructor variable. This change reflects the structure ofIndexWrapperbefore opendistro-for-elasticsearch/k-NN@7640186.Add unit test. The unit test sometimes reproduces the issue. However, it is difficult to reproduce deterministically. I was able to reproduce on my mac fairly consistently, but not able to reproduce on linux.
