MariaDB crashes when compiled with link time optimizations

    Description

      Following the release of MariaDB 10.5.10 on Hirsute, we have discovered that appending -flto and -ffat-lto-objects as compile flags will cause MariaDB to crash with SIGABRT in pthread_exit when closing the replication slave thread.

      This is happens regardless if MariaDB is compiled with PERFSCHEMA or not.

      Steps to reproduce:

      Set up an Ubuntu 21.04 docker container or VM.

      run

      debian/autobake-deb.sh

      or

      dpkg-buildpackage --build=binary

      from the base server directory.

      Notice the extra -flto and -ffat-lto-objects flags being passed during compilation (and linking).

      Run any replication test such as rpl_sp
