This jira issue concludes by suggesting not to use minPoolSize in mongocxx::uri object instantiation for a mongocxx::pool. When used irrespective, it throws a deprecation warning and along the line I get a SegFault. I’m not sure the SegFault is related but if it is, I think these should be documented.
Steps to reproduce:
MongoCXX 3.8
Instantiate mongocxx::uri with url having query param minPoolSize.
