I finally managed to capture a few non-corrupted crashdumps.
The cause of crash always points to the same symbol:

Also, I would like to reiterate that these crashes happen AT THE VERY
MOMENT the xl save command is executed. I experimented with delaying
the xl save by a few seconds, even minutes. The VM runs always fine
until the moment xl save is executed. Then this crash happens
(randomly).
