GEMDOS HD isn't needed, but one needs to add at least 8 MB of TT-RAM,
otherwise outside crashes when run from AUTO:
	--machine tt --ttram 8 --addr24 off --mmu on

It takes maybe 15s for mouse cursor to freeze and at least additional
minute until Hatari crashes.

Unfortunately, it seems random whether Hatari crashes.  Mostly
there's just double bus error under emulation.  Under GDB, I've
been getting just the latter.


Bombs happens also with these, which make reproducing them faster:
	--cpu-exact off --compatible off --fast-boot on

And also under Falcon emulation:
	hatari --machine falcon --dsp none --tos tos404.img \
	   -s 4 --ttram 8 --addr24 off --mmu on --scsi outside.img


Valgrind gave me following warnings before the bombs, but Hatari
never crashed:

PS. I cannot test this with EmuTOS.  While EmuTOS runs "outside.prg"
from auto (see "--trace os_base" output), it always complains that
there isn't enough memory to run "outconf.app" regardless of how
much memory I set in Hatari (e.g. 14 + 64 MB).
