    Description

      This backtrace is from a failure in prepare_requires_fcv42.js that is reproducible using my patch in SERVER-36023 (activating transactions testing with the inMemory storage engine) – see that ticket for repro specifics. The failure happens before FCV is downgraded, so it's not a version compatibility issue, despite the test. The patch for SERVER-36023 generally produces this error in lots of different tests.

      It was suggested that SERVER-35811 should fix this failure, but there are concerns that this isn't an active known failure – i.e. that it should not be failing in master right now. So I'm filing this ticket, so that it can either be confirmed that we known about it, or confirmed we need to fix it more urgently than SERVER-35811.

      There were similar test failures with index builds, that were introduced and then fixed during v4.0 dev by SERVER-34172. It is thought that perhaps the prepare transactions path is causing some similar trouble, as it was not used/tested much previously, but this hasn't been explored.
