I recently had to revert a change from develop, when the patch test for the WT drop failed the UBSAN testing in MongoDB. Possibly we could have caught this earlier if we also did UBSAN testing in WT.
We can upgrade our ASAN to test undefined behaviour as well or add a new variant.
This ticket should first check if we already test UBSAN or not. If not, either upgrade ASAN test job to test UBSAN as well, or create a new job.
