Description

I think this is perhaps from TS-4858:

*** CID 1364311:  Memory - illegal accesses  (USE_AFTER_FREE)
/iocore/net/SSLConfig.cc: 258 in SSLConfigParams::initialize()()
252       ats_free(ssl_server_ca_cert_filename);
253       ats_free(CACertRelativePath);
254     
255     #if HAVE_OPENSSL_SESSION_TICKETS
256       REC_ReadConfigStringAlloc(ticket_key_filename, "proxy.config.ssl.server.ticket_key.filename");
257       if (this->ticket_key_filename != NULL) {
   CID 1364311:  Memory - illegal accesses  (USE_AFTER_FREE)
   Passing freed pointer "this->ticket_key_filename" as an argument to "relative_to".
258         ats_scoped_str ticket_key_path(Layout::relative_to(this->serverCertPathOnly, this->ticket_key_filename));
259         default_global_keyblock = ssl_create_ticket_keyblock(ticket_key_path);
260       } else {
261         default_global_keyblock = ssl_create_ticket_keyblock(NULL);
262       }
263     #endif
