### Description
Kamailio fails to start after recent changes were made to improve support for OpenSSL 3.X.
The failure occurs for both OpenSSL 3.X and OpenSSL 1.1.X, and are the same as failures I
had been seeing on previous Kamailio versions when using OpenSSL 3.X. These errors were
not occurring for OpenSSL 1.1.X prior to commits on Jan 4, 2024.
My configuration is using the unixodbc module to communicate with a Microsoft SQL Server
database. Furthermore, the dispatcher module is configured to use the database.
With this configuration, Kamailio always fails at startup. It may log a "freeing
already free pointer bug" or sometimes indicates pointer corruption. In either case,
it fails to connect to the database.
#### Reproduction
Start Kamailio with configuration files similar to the following. For the log file shown
below, Kamailio was started with "kamailio -dd -E --atexit=no"
