This is not new. Any CPU mode without "more compatible" enabled will crash if CPU's opcode fetch accesses non-existing memory. It is performance optimization.

It is near guaranteed when switching from 68010+ to 68000 CPU due to different exception/interrupt stack frames. Don't do it. It is never going to work, even if it isn't going to crash.
