ProduceAsync segmentation fault on a specific produce configuration · Issue #2084 · confluentinc/confluent-kafka-dotnet · GitHub

ProduceAsync with certain lengths of ProducerConfig.ClientId and TopicName strings leads to an invalid memory access and a segmentation fault.

var message = "1";

var bootstrapServers = "<your bootstrap servers>";

var topicName = new String('a', 69);
var clientId = new String('a', 239);

var config = new ProducerConfig
{
	BootstrapServers = bootstrapServers,
	ClientId = clientId,
};

var builder = new ProducerBuilder<string, string>(config);
var producer = builder.Build();

await producer.ProduceAsync(topicName, new Message<string, string>()
{
	Value = message
});

You can reproduce it with confluent.kafka nuget versions 2.2.0 and 2.1.1.
It can't be reproduced with confluent.kafka nuget version 1.9.3.

Apache Kafka 2.8.1
