When using a gcc 13.2.0 devkit, the Linux builds (x86_64 and ppc64le) fail with warnings as errors in case that ubsan is enabled.
The 2 warnings as errors are about memset usages ; we see those issues with gcc 13.2 but did not see it with previously used gcc 11.
They only occur with ubsan enabled (seems the warnings change a bit in this case).
