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

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

I'm using 512k version, md5sum is cee17f68e8dc0bd3a35816650e44fe90

Can you try after removing hatari.cfg to be sure we have the same defaults to do this test ?

Segfaults with defaults when enabling 030 & MMU.

I removed hatari.cfg and then ran :

./hatari    --machine tt --tos ~/Emul/ST/tos/emutos097.img -s 8 --ttram 0 --mmu on --addr24 off

I then press alt+c at the emutos boot page where it says to press shift to pause the screen, but hatari never crashes for me.

Often I wait until EmuTOS boots to the desktop, then it's always been
enough to press AltGr+C 1-2 times (>90% of time, once is enough, and
second press can be done before welcome screen).

Now that I re-tried doing it right at welcome screen, there was one
time where I had to use AltGr+C a dozen times before segfault.  Maybe
EmuTOS initializes MMU right after welcome screen, or at least does
some extra MMU settings after it?

I don't understand your scenario. In your first email you wrote "use AltGr-C to cold boot after EmuTOS bootup logo " which is right after boot, but now you say you need to wait for desktop to appear ?

Then you say to press alt+c several times, do you mean you need to press it after desktop appears, then machine resets, then screen goes white, then you press alt+c again before emutos logo and machine summary appears ?

Maybe you could post a small video somewhere ?

Maybe this crash is created by some specific optimisation flags / gcc version ? That would be the 1st time it happens, but who knows (I'm comiling for 64 bit architecture, are you using 32 bit maybe ?)

32bit version, gcc v6.3.

I have an other PC which is still running linux 32 bit, I will try on it too.
