Memory leak bug

The following code causes a memory leak on Linux:

using (var connection = new MySqlConnection(_connectionString))
{
    await connection.OpenAsync();

    using (var transaction = connection.BeginTransaction())
    using (var command = new MySqlCommand(connection, transaction))
    {
        command.CommandText = "SOMESQL";
        command.ExecuteNonQuery();

        command.CommandText = "SOME OTHER SQL";
        command.ExecuteScalar();

        transaction.Commit();
    }
}

I couldn’t investigate it further, but lldb with the SOS plugin shows System.String containing the queries accumulating in the heap.

Please let me know if you would like some more details.

I opened #275 to track SslStream not being disposed.

Apologise if I wasn’t able to cut some time to test, I will send some updates if we get back to it.
