   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/pulsar-client-cpp/issues) and found nothing similar.
   
   
   ### Version
   
   Client 3.5.0
   
   ### Minimal reproduce step
   
   Create a `main.cc`
   
   ```c++
   #include <chrono>
   #include <pulsar/Client.h>
   using namespace pulsar;
   
   int main(int argc, char *argv[]) {
     Client client{"pulsar://localhost:6650"};
     std::string topic = (argc > 1) ? argv[1] : "my-topic";
     Producer producer;
     if (auto result = client.createProducer(topic, producer);
         result != ResultOk) {
       std::cerr << "Failed to create producer: " << result << std::endl;
       return 1;
     }
   
     producer.send(MessageBuilder().setContent("msg-0").build());
   
     Reader reader;
     if (auto result =
             client.createReader(topic, MessageId::latest(), {}, reader);
         result != ResultOk) {
       std::cerr << "Failed to create reader: " << result << std::endl;
       return 2;
     }
   
     using namespace std::chrono;
     reader.seek(
         duration_cast<milliseconds>(system_clock::now().time_since_epoch())
             .count());
   
     bool hasMessage;
     if (auto result = reader.hasMessageAvailable(hasMessage);
         result != ResultOk) {
       std::cerr << "hasMessageAvailable failed: " << result << std::endl;
       return 3;
     }
   
     std::cout << hasMessage << std::endl;
   
     return 0;
   }
   ```
   
   Key point: the start position must be `latest` for `Reader`.
   
   On macOS m1, install the the macos-arm64.zip and build with those artifacts.
   
   ```bash
   curl -O -L https://archive.apache.org/dist/pulsar/pulsar-client-cpp-3.5.0/macos-arm64.zip
   unzip -q macos-arm64.zip
   g++ main.cc -std=c++17 -I ./include -L ./lib -Wl,-rpath ./lib -lpulsar
   ./a.out
   ```
   
   ### What did you expect to see?
   
   Outputs (ignore the outputs from the library):
   
   ```
   1
   ```
   
   ### What did you see instead?
   
   The output should be 0 like the behavior with 3.4.2
   
   ```bash
   curl -O -L https://archive.apache.org/dist/pulsar/pulsar-client-cpp-3.4.2/macos-arm64.zip
   unzip -q macos-arm64.zip
   g++ main.cc -std=c++17 -I ./include -L ./lib -Wl,-rpath ./lib -lpulsar
   ./a.out
   ```
   
   Outputs:
   
   ```
   0
   ```
   
   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   - [X] I'm willing to submit a PR!
