I used to test my builds with Virtualbox and it worked just fine for me. The
official ISO image 2016-05-01 boots without issue, same for an image I built
on 2016-05-11 at 10 am.

It fails since one day later, so anything changed between 2016-05-11 at 10 am
and 2016-05-12 late afternoon.
main(a){char*c=/*    Schoene Gruesse                         */"B?IJj;MEH"
"CX:;",b;for(a/*    Best regards             my address:    */=0;b=c[a++];)
putchar(b-1/(/*    Chris            cc -ox -xc - && ./x    */b/42*2-3)*42);}
