Even with 256 MB, it doesn't crash for me

I think that's because that was the max I found in some memory 
extensions that were sold at this time :)
Theoretical address are between 0x01000000 and 0x80000000, which would 
be 2047 MB.
Current max limit could be raised above 256 MB if it doesn't create any 
problem with TOS

Can you send the command line you run to get the crash ?

I run :

../hatari  --machine falcon --tos ~/Emul/ST/tos404.img --ttram 256 
--addr24 false

and there's no crash when desktop appears.

Does it crash if you don't boot with HD emulation but only with an empty 
floppy for example ? (maybe the problem is caused by some extra *.ACC or 
auto/ file ?)
