Triaging old bug tickets... can you still reproduce this issue with the
latest version of QEMU? Or could we close this ticket nowadays?

Title:
  assertion failed in exec.c while attempting to start a guest (latest
  commit)

Status in QEMU:
  Incomplete

Bug description:
  Hi team,

  I decided to try the latest commit on git (previously used version
  1.3.0), and I got failed assertions while attempting to start my
  guests:

  eclipse ~ # qemu-kvm -enable-kvm -hda arch.img -m 4096 -smp sockets=1,cores=4 
-vnc :0 -cpu host -vga std -net nic,model=e1000,macaddr=00:00:00:00:00:00 -net 
tap,ifname=vm0 -qmp tcp:0.0.0.0:4900,server,nowait
  qemu-kvm: /var/tmp/portage/app-emulation/qemu-9999/work/qemu-9999/exec.c:982: 
qemu_ram_set_idstr: Assertion `!new_block->idstr[0]' failed.
  Aborted

  The assertion seems valid, so whatever's causing it is probably to
  blame. I haven't dug around much to find out what calls the method
  (qemu_ram_set_idstr()), but that is probably the best place to start.

  The host contains a Xeon E3-1240 CPU, virtualising a bunch of guests
  one of which is Arch Linux 64-bit, if that helps.

  eclipse ~ # qemu-kvm -version
  QEMU emulator version 1.4.50, Copyright (c) 2003-2008 Fabrice Bellard

  It looks like this assertion happens if you call the executable
  without any parameters as well:

  eclipse ~ # qemu-kvm
  qemu-kvm: /var/tmp/portage/app-emulation/qemu-9999/work/qemu-9999/exec.c:982: 
qemu_ram_set_idstr: Assertion `!new_block->idstr[0]' failed.
  Aborted

  Thanks.
