last worked fine in WinUAE2.3.1 2011-02-26 ... broken in WinUAE2.3.2 2011-06-02 !!!!!!
It didn't really work any better. It just timing difference, it wasn't correct in old version, it isn't correct now. It is just differently wrong..

Corruption happens because CPU modifies bitplane pointers in copperlist after copper has fetched high word but before copper fetches low word of bitplane.

EDIT: It is only few clock cycle difference between corruption or not having corruption which means timing change in any instruction, even really tiny, will "fix" this again..
