[Qemu-devel] Commit 23326164ae (exec: Support 64-bit op...) triggers assertion

[Luiz Capitulino]

Hi,

Reproducer:

# ./qemu-qmp -drive file=disks/test.img,if=virtio,cache=none,aio=native \
  -enable-kvm -m 1G -monitor stdio  -usb -usbdevice host:1.43
QEMU 1.5.50 monitor - type 'help' for more information
(qemu) qemu-qmp: /home/lcapitulino/work/src/upstream/qmp-unstable/exec.c:1927: 
memory_access_size: Assertion `l >= access_size_min' failed.

I have an USB stick on 1.43, although I did manage to get this without
USB at all (forgot how, though).
