I remember that we had to fix bus error handling in the old UAE core a

stack frames as Andreas already discovered).
I'm quite busy this week, but if somebody wants to have a look, check
the exception functions in cpu/newcpu.c for the right bus error stack
layout...
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:
http://hg.tuxfamily.org/mercurialroot/hatari/hatari/log/tip/src/uae-
cpu/gencpu.c
E.g. the "Fix return PC when JMP generates an illegal address exception"
wasn't applied to WinUAE core:
http://hg.tuxfamily.org/mercurialroot/hatari/hatari/log/tip/src/cpu/gencpu.c
Another one could be here:
http://hg.tuxfamily.org/mercurialroot/hatari/hatari/log/tip/src/uae-
cpu/newcpu.c
"While processing an exception, raise an address error exception if
the new PC is not even" isn't mentioned in WinUAE log:
http://hg.tuxfamily.org/mercurialroot/hatari/hatari/log/tip/src/cpu/newcpu.c
For exceptions there's just some commits for MMU and for disabling
Amiga specific stuff.
