    So I've tried running your .config in both an AMD and an Intel guest
    like this:

    ./syz-execprog -repeat=0 repro.syz

    and killed it after 30K executed programs without success in
    reproducing.

    Either I'm missing something and my environment doesn't match yours -
    because looking at your console output it happens almost immediately
    after starting - or it has been fixed in the meantime...

    Hmmm.
