I can't reproduce the crash when using:
	--cpu-exact off --compatible off

But if I remove either (or both) of those options, Hatari
segfaults reliably on AltGr+C, also with your set of options.

(Sometimes the segfault happens only when pressing AltGr-C
second time, but that's rare.  I'm not sure whether there's
some pattern when pressing it second time is needed.)

Cycle exact mode is the default, that's why I didn't
specifically enable it.

Did you have 256k or 512k version of EmuTOS v0.9.7?

(192k version doesn't support MMU and can't trigger the bug.)

Segfaults with defaults when enabling 030 & MMU.
