Hi  Mikael,

I just tried another approach to fix this issue, see:

https://review.lttng.org/c/lttng-ust/+/9413 Fix: use unaligned pointer accesses for lttng_inline_memcpy

It is less intrusive than other approaches, and does not change the generated code on the
most relevant architectures.

Feedback is welcome,

Thanks,

Mathieu
