Jan 3, 2025

View in context in the libbitcoin Slack #general mirror.

on a fresh install on debian 12, bn was working. Then I executed ./bn -t

./bn -t
Using default configuration settings.
Database is started.
Getting first [100] output address hashes.
Segmentation fault

and now bn doesn't run anymore
