Raghunandan Bhat b22095a920 MDEV-31850: SIGSEGV in Item::print_parenthesised | Item_cond::print
Problem:
  During the execution of function, the `WHERE` clause in the function's
  cached definition is incorrectly reassigned. This assignment points to
  a transient copy, which is then modified during query preparation and
  optimization. When the execution's memory arena is cleaned up, this
  transient copy is freed leading to a crash if SHOW FUNCTION CODE tries
  to access it.

Solution:
  The `WHERE` clause is now correctly managed by creating a disposable
  copy for each execution. This copy can be safely optimized and
  discarded, without affecting the cached function definition.

MariaDB: The innovative open source database

MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.

MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.

MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.

MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.

A description of the MariaDB project and a manual can be found at:

Getting the code, building it and testing it

Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
