Thanks for trying to fix this, but without coverage on the topic, it
is likely we will have new errors in the future.
Now that the trace framework has been fixed (856aef55de95 ("trace: fix
undefined behavior in register")), enabling UBSan in the CI has become
easier.
Could you spend some time on reviewing patches on the topic?
Like for example: https://patchwork.dpdk.org/project/dpdk/list/?series=35509

rte_malloc is not required.
I have a fix in an branch of mine, that makes use of aligned_alloc
(which is C11), you need to manually copy data in stats_mem_populate.
