Re: [Freemint-discuss] XaAES often crashes during boot after a reboot

Hi,

somehow I had completely overlooked your test program, especially when you
say that 0x55 makes it crash almost instantly.

I'm getting very similar vibes here as from
https://github.com/freemint/freemint/issues/273#issuecomment-1832685444.

I'll try this at some point, ideally in Hatari or Aranym.
