LevelDB corruption on macOS Big Sur beta #19410
Description
For more problems with macOS Big Sur (beta) see #19406.
I first ran the binary release v0.20.0 and it synced at least a few dozen blocks without issue (around height 604,000).
Depends built with: make NO_ZMQ=1 DEBUG=1 NO_QT=1 NO_WALLET=1
Configured with: ./configure --enable-debug --enable-werror --prefix=/Users/sjors/dev/bitcoin/depends/x86_64-apple-darwin20.0.0
On an existing node, bitcoind crashes at different heights, and often for different ldb files. Example log:
src/bitcoind -debug=leveldb

2020-06-29T12:12:53Z Error: Error reading from database, shutting down.
When building without depends or using the 0.20 release, afterwards, results in the same errors, so most likely those files are actually corrupt.
I'm syncing a node (built with depends) from scratch. So far no crash (height=225,000).
Unless someone else sees this (which could suggest an upgrade issue), I'll close this in a while.
