BewareMyPower opened a new pull request, #432:
URL: https://github.com/apache/pulsar-client-cpp/pull/432

   ### Motivation
   
   There is a case that `libpulsar.so` could unexpectedly call functions from 
other dependencies.
   
   For example, assuming the application depends on two libraries:
   - `libpulsar.so`, which includes the symbols from `libcurl.a` 8.4.0
   - `libfoo.so`, which includes the symbols from `libcurl.a` 7.82.0
   
   If the link order is `libfoo.so` first, then the libcurl definitions from 
7.82.0 will also be used by `libpulsar.so` and then the application might crash 
due to the incompatibility. This is an issue specifically with Linux ELF format.
   
   ### Modifications
   
   Add the `-Wl,-Bsymbolic` link option for GCC.
