good news is that I can duplicate the crash when using a 32 bit build. 
This looks like some memory being overwritten at some points, because 
when I add some debug printf, some of those printfs make the crash 
disappear ...

So far, I see that the crash happens just after the reset, the 1st 
instruction after the reset get a bus error when being fetched.
I think it's a bug in hatari, because PC is not the correct value at 
this point, so when mmu is on, this calls mmu030_page_fault() and this 
is more or less where the crash happens (I still need to add more traces 
to see what part of the code can trigger the bus error).

But I think the source of the bug is in Hatari, not in WinUAE.
