MMU support is not that old, 030 MMU + cache
support was added some time in 2017, and many bugs
were still fixed in 2018.

Do you remember how long ago the above combo was
fully working (in winAUE CPU core version)?

There were quite a lot of mystery crashes on user-
space entry / exit also earlier, so I'm not too
surprised about that. :-)

I was testing Hatari version that had Nicolas' CPU core updates from 
yesterday.

I'll hope to have time to bisect it this evening.
Happily it's fully reproducible.
