[Bug] subscribeAsync and createProducerAsync return UnknownErrorCode when built using devtoolset-11

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar-client-cpp/issues) and found nothing similar.

### Version

OS: CentOS 7
Pulsar C++ client: 3.1.2

### Minimal reproduce step

1. Install gcc 11.
```
yum install devtoolset-11
. /opt/rh/devtoolset-11/enable
```

2. Install the same dependencies as this Dockerfile:
https://github.com/apache/pulsar-client-cpp/blob/v3.1.2/pkg/rpm/Dockerfile

3. Build rpm using this spec file:
https://github.com/apache/pulsar-client-cpp/blob/v3.1.2/pkg/rpm/SPECS/pulsar-client.spec

4. Install pulsar client library.
```
rpm -ivh apache-pulsar-client*.rpm
```

### What did you expect to see?

#subscribeAsync and #createProducerAsync return ResultOk.

### What did you see instead?

#subscribeAsync and #createProducerAsync return UnknownErrorCode.
When I tried to output the value of return value, it returned unexpected values like 1915086316.

### Anything else?

When built using gcc-toolset-11 on Rocky Linux 8, #subscribeAsync and #createProducerAsync return ResultOk.

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Reproduisez le problème sur CentOS 7 avec devtoolset-11 en utilisant pkg/rpm/Dockerfile et pkg/rpm/SPECS/pulsar-client.spec. Suivez subscribeAsync et createProducerAsync afin de déterminer pourquoi leurs valeurs retournées deviennent UnknownErrorCode, puis vérifiez que les deux retournent ResultOk avec des valeurs valides dans le build signalé.
