Title:
  qemu-system-arm segmentation fault with cpu cortex-m*

Status in QEMU:
  Invalid

Bug description:
  I try to run an emulation with qemu-system-arm under a cpu cortex-m3
  but any execution under the processor result by a segmentation fault.

  My command is : qemu-system-arm -m 256 -M versatilepb -cpu cortex-m3
  -kernel ~/qemu/wheezy/vmlinuz-3.2.0-4-versatile -initrd
  ~/qemu/wheezy/initrd.img-3.2.0-4-versatile -hda ~/qemu/wheezy/hda.img
  -append 'root=/dev/sda1'

  If a lauch the emulation without specifying a cpu equivalent to
  cortex-m*, the vm opens up well and works but I absolutely need to run
  it under cortex-m3.

  
  Do you have any idea why I have this problem only with this type of processor 
?

  I also try with other boards different from versatilepb but I have the
  same result.

  I am under ubuntu 17 64bits during my test.
