`transaction/2` Bus Error in Pessimistic Mode

[koudelka]

Hi friends, I'm sure I'm holding it wrong, but I'm seeing a Bus Error upon attempting to open a transaction in pessimistic mode on 27226d9.

Erlang/OTP 26 [erts-14.1.1] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit]

Interactive Elixir (1.16.0) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> {:ok, db} = :rocksdb.open('abcd', [create_if_missing: true])
{:ok, #Reference<0.3067529985.887488542.124224>}
iex(2)> :rocksdb.transaction(db, [])
[1]    66041 bus error  iex -S mix

However, opening the db in optimistic mode seems to work:

iex(1)> {:ok, db, _} = :rocksdb.open_optimistic_transaction_db('abcd', [create_if_missing: true])
{:ok, #Reference<0.730962756.82182167.104348>,
 [#Reference<0.730962756.82182167.104349>]}
iex(2)> :rocksdb.transaction(db, [])
{:ok, #Reference<0.730962756.82182145.106604>}

Hi @koudelka !

Thanks for the report. However, please note that this is a fork of erlang-rocksdb. 😅
