As pointed out with MDEV-29308 there are issues with the code as is. MariaDB is built as C++11 / C99. aligned_alloc() is not guarenteed to be exposed when building with any mode other than C++17 / C11. The other *BSD's have their stdlib.h header to expose the function with C+11 anyway, but the issue exists in the C99 code too, the build just does not use -Werror. Linux globally defines _GNU_SOURCE hiding the issue as well.
