I try to run the cloud example but I get a coredump

./cloud_durable_example

I manually fix this buy adding one line

diff --git a/cloud/aws/aws_s3.cc b/cloud/aws/aws_s3.cc
index 1eecf7b22..f47c6524c 100644

  Aws::Client::ClientConfiguration config;
  Status status = AwsCloudOptions::GetClientConfiguration(
      cfs, cloud_opts.src_bucket.GetRegion(), &config);

Is this a bug? Or do I use it in the wrong way?
