To be more specific, it's not crashing qemu. It just brings the
emulated system in a condition in which it won't function (trap after
the maximal trap level is reached). So it's not necessarily a...
bug. Can be a virtio/kernel bug as well.
But there is a point in Marks reply: maybe nowadays virtio-net also
has to be switched into the legacy mode.
Instead of "-net nic,model=virtio -net user" can you please try:
-netdev user,id=hostnet0 -device
