No, it's not new. Some games/demos sometimes do address errors on 
purpose to avoid testing the end of a list of value in very optimized 
code (better brute-read data always and have a rare slower case just in 
a few cases).
Difference in old uae cpu core was that those messages were removed or 
shown less frequently after a certain count was reached.
I will remove them later once everything seems fine.
