This tells me very little ;)

Can you please provide more details? e.g. What is the error you are getting? How
do I reproduce it?

I am happy to include the required change as part of this series.

Overall, the reason why I am doing this exercise it to sanitize the headers for
all the architectures so that in future we do not have issues. It is good we
find problems now.
