Starting with a database that reliably segfaulted everytime, I updated and ran the following version and see the problem is fixed: 3.36.0 2021-05-24 14:35:19 17960165f5840cab45b7a8bb02779ebfb321c68f33ec6da9ab14063ccd134fa4 Many thanks for the fix and sorry I couldn't provide a small reproduction - thank you again for spending the time to figure it out, and your description on the change looks accurate to to the code I'm running too.
