Vertica client 9.0.1 potential memory leak

I am connecting to vertica database (running version 9.0.1-6) with a client 9.0.1-4 and odbc version 3.52.7-7 on red-hat 7.6. Running valgrind on a simple example program found in the documentation (https://vertica.com/docs/9.0.x/HTML/index.htm#Authoring/ConnectingToVertica/ClientODBC/ConnectingToVertica.htm?TocPath=Connecting%20to%20Vertica|Client%20Libraries|Programming%20ODBC%20Client%20Applications|_____5) reports memory leaks (full output below). Am I missing something?
