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

Mariadb installation：
1) cd mariadb-10.8.3
2) mkdir build; cd build
3) cmake .. -DCMAKE_BUILD_TYPE=Debug
4) make -j12 && sudo make install

Test driver compilation:
Note: "mariadb_reproduce" sets up several transactions and execute SQL statements according to /tmp/mysql_bk.sql, /tmp/stmts.sql and /tmp/tid.txt
1) g++ -I/usr/local/mysql/include/ mariadb_reproduce.cc -o mariadb_reproduce -lmysqlclient -g

Reproduce the bug:
1) cp mysql_bk.sql /tmp; cp stmts.sql /tmp; cp tid.txt /tmp
2) export ASAN_OPTIONS=detect_leaks=0
3) /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql &
4) bash reproduce.sh # "reproduce.sh" repeatedly executes "mariadb_reproduce" 100 times. "reproduce.sh" and "mariadb_reproduce" should be in the same directory

I have simplified the content of fuzz.sql, and I hope fuzz.sql can help you reproduce and fix the bug. In addition, I attached the failure report (which has its stack trace).

This bug seems related to concurrency and it cannot be reproduced stably. However, it did occur and crashed the server in my test. To stably trigger this bug, I use "reproduce.sh" to execute "mariadb_reproduce" 100 times. Hope you could reproduce the bug successfully
