dinghram opened a new issue #13927:
URL: https://github.com/apache/pulsar/issues/13927
**Describe the bug**
When compiling pulsar-client-cpp in pulsar 2.8.2, there is an ambiguous call
to subscribe in ConsumerTest.cc.
**To Reproduce**
Steps to reproduce the behavior:
1. Compile pulsar-client-cpp
**Expected behavior**
CPP client compiles
**Desktop (please complete the following information):**
- CentOS 7

A simple solution is to cast the initializer list as a
std::vector<std::string> in the call to subscribe.
