I am running Bitcoin Core 0.17.0
No useful info in debug.log Crash occurs on start of upgrading txindex

I have been running Bitcoin Core on this machine since version ~0.14.0, and have run every version since then (including this recent 0.16.3). I have never run into any crash like this until this install.

Problem reported as:

bitoin-qt killed by SIGBUS
Likely crash reason: Jump to an invalid address
