Steps to reproduce

First, start a container:

mvn clean install -DskipTests -Pcore-modules,-main
docker run -v $PWD:/pulsar -it apachepulsar/pulsar-build:ubuntu-20.04 /bin/bash

Then, run the following commands inside the container:

# Build the unit test (increase the docker memory if segfault happened, or remove -j4 option)
cd /pulsar/pulsar-client-cpp/
cmake -B _builds -DBUILD_DYNAMIC_LIB=OFF -DBUILD_PERF_TOOLS=OFF -DBUILD_PYTHON_WRAPPER=OFF
cmake --build _builds -j4

# Run the standalone
cd /pulsar/distribution/server/target/
tar zxf apache-pulsar-*.tar.gz
cd apache-pulsar-*-SNAPSHOT
./bin/pulsar-daemon start standalone -nss -nfw

# Run the test for multiple times
cd /pulsar/pulsar-client-cpp/_builds
./tests/main --gtest_filter='ClientTest.testReferenceCount' --gtest_repeat=10
