With the log enabled, I used `docker exec -it 589ae68de943 bash` to attach to the running container and `tail -f /tmp/sql.log` to see the logs. Here's where it broke: ``` select count(*) from [idx_civici_geom_parent]: None select count(*) from [sqlite_stat1]: None select count(*) from [sqlite_stat3]: None select count(*) from [SpatialIndex]: None ``` So attempting to run a `count(*)` against the `SpatialIndex` virtual table is the thing that triggers the bug. | {"total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} | 837308703 |
