Yes, same problem with type=street and type=associatedStreet relations.
I've added diverse checks to make sure that they are ignored when the names
do not match, but these checks will only work when your style rules
don't use the relations to name relation members without checking.

So, I think rules like 
type=associatedStreet { apply role=house { add addr:street='${name}' }}
should be avoided since r3359 if you want to use the messages produced
by mkgmap to correct wrong data.

So, my conclusion: It the style author who decides what's right or wrong,
the value in mkgmap:street gives the street name for address search.
