    Description

      I used my fuzzing tool to test Mariadb , and found a bug that can result in an abortion.

      Mariadb installation:
      1) cd mariadb-10.5.9
      2) mkdir build; cd build
      3) cmake -DWITH_ASAN=ON -DWITH_ASAN_SCOPE=ON -DCMAKE_BUILD_TYPE=Debug ../
      4) make -j8 && sudo make install

      How to Repeat:
      export ASAN_OPTIONS=detect_leaks=0
      /usr/local/mysql/bin/mysqld_safe &
      /usr/local/mysql/bin/mysql -uroot -p123456(your password)
      MariaDB> drop database if exists test_db;
      MariaDB> create database test_db;
      MariaDB> use test_db;
      MariaDB> source fuzz.sql;

      I have simplified the content of fuzz.sql (this one is still very complicate), and I hope fuzz.sql can help you reproduce the bug and fix it. In addition, I attach the failure report (which has its stack trace).
