memcached is currently FTBFSing on ppc64el when built with GCC 12. The test has been performed in Ubuntu, but this will also affect Debian when GCC 12 becomes the default.

I submitted a PR upstream to fix the issue, but they haven't replied/reviewed it yet:
https://github.com/memcached/memcached/pull/905
Although this is not a problem in Debian for now, I believe it's better to adopt the fix here instead of adding an unnecessary delta to memcached in Ubuntu.
Thanks!
