Hi, Paolo, It was an incredibly fast fix! :) I already confirmed that the fix fixes the problem on msa_helper.c. I would nevertheless like to have this workaround applied. Can you perhaps give it "Reviewed-by"?

Without this patch, they wouldn't. > What is unclear to me is, while changing this, why only fix > the suffix and not also the prefix?
