If this is the case, I agree with the warning, but why is it placed in
function 'bbb', and not in 'ggg'? 'ggg' is the one that converts from
unsigned char to Fffff.
I believe this is a bug that message is misplaced. This makes message
misleading and confusing.
Message line should be fixed, and also it should be one message, not two.
This case should be reopened.
Thank you,
