Not only is the application (dynamically) linked against two different
versions of OpenSSL's crypto library, it is also using both Heimdal and
MIT Kerberos, which may also cause some confusion if symbol versioning
does not fully take care of the overlapping APIs.

Heimdal might be linked against OpenSSL.

It is also often built against OpenSSL, the choice is rather platform-dependent.
This application is a classic case of DLL-hell. On the OpenSSL side, it could
benefit from the "shlib_variant" feature of the 1.1.1 builds. But if the base
system's OpenSSL libraries are adequate, the OP may be better off just using
