I noticed that there was one exception handling fix in v1.6.2 to old UAE
core by Nicolas that doesn't seem to have been applied to WinUAE core:
E.g. the "Fix return PC when JMP generates an illegal address exception"
wasn't applied to WinUAE core:
Another one could be here:
"While processing an exception, raise an address error exception if
the new PC is not even" isn't mentioned in WinUAE log:
For exceptions there's just some commits for MMU and for disabling
Amiga specific stuff.
