From the stack of the crash, we observed that the crash occurs when the product deallocates memory after communicating with the KDC. It could be a double free on the memory liberation or a corrupted memory segment or file descriptor.
This communication mechanism is changed in latest KRB5 with improvements which have been included to the 12.52 SP1 CR8 Policy Server
Upgrade to the 12.52 SP1 CR8 Policy Server or above:
DE159909 - The Kerberos libraries are upgraded to Release 1.11.
