Trying to run an application using JDBC 18c or 19c against an Oracle 19C database fails with exception:

INFO | jvm 1 | 2020/04/22 12:21:40 | 12:21:40,534 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-1) SQL Error: 17410, SQLState: 08000
INFO | jvm 1 | 2020/04/22 12:21:40 | 12:21:40,534 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-1) No more data to read from socket

At the database side, the following error is reported:

ORA-07445: exception encountered: core dump [qkacco()+91] [SIGSEGV] [ADDR:0x0] [PC:0x2844D7B] [Address not mapped to object] []

19C is fully patched with database Patch 30783543 - Combo of OJVM Component Release Update + Database Apr 2020 Release Update

The same application works fine against Oracle  database 18c.
