Attached is a new reproducer that just uses the libmysqlclient directly without using Qt.
It's based on an example from a zetcode tutorial.
I used this to compile it :-
gcc mysql_test.c -o mysql_test -I/usr/include `mysql_config --cflags --libs`
The interesting thing is if you comment out both mysql_server_end() and mysql_library_end() at the bottom of the example it works without segfault. Uncomment either call and it will segfault.
This is the bt with debugging symbols installed for libmysqlclient which is a little more informative and should help a MySQL dev pinpoint the problem.
(gdb) bt
#0 0x00007ffff793823f in charset_uninit () at ./mysys/charset.cc:925
#1 0x00007ffff793d753 in my_end (infoflag=infoflag@entry=0) at ./mysys/my_init.cc:200
#2 0x00007ffff78db173 in mysql_server_end () at ./libmysql/libmysql.cc:202
#3 0x00005555555554f0 in main ()
I'll also attached a bt with bt full in case it's useful.

The mysql docs say mysql_server_end() is depreciated and new code should use mysql_library_end() but they both cause a segfault. Ref: https:/ /dev.mysql. com/doc/ refman/ 8.0/en/ mysql-server- end.html
