Is this the right list for sqlite4 bugs?
I have sqlite4 build fde11ff78c433d66 and a largish database. When I drop one
of the indices on it through the sqlite4 command line tool, the tool dies with
a BUS ERROR. For this database file it reproduces 100% of the time for me. I
have the gdb backtrace below. I can share the database but it's quite large so
I'd rather not upload it unless someone thinks they can actually make use of it.
1.7G database.db
347M database.db-log
2.0G database.db-shm
$ gdb $(which sqlite4) --args sqlite4 databasedb/database.db "drop index
idx_followers_main; create index idx_followers_main on followers(hash,
next_token, count)"
This GDB was configured as "x86_64-apple-darwin"...Reading symbols for shared
libraries .. done
