QEMU crashes when there is an "[accel]" section in the config file

Host environment

  • Operating system: Linux
  • Architecture: x86
  • QEMU flavor: qemu-system-x86_64
  • QEMU version: current master branch (commit 3db29dca)

Description of problem

QEMU crashes with a segmentation fault if there is a "[accel]" section in the config file with a type="kvm" entry. It would be maybe still be OK if there was an error message instead, but it should certainly not crash.

Steps to reproduce

$ cat > /tmp/config <<EOF
[accel]
type = "kvm"
EOF
$ qemu-system-x86_64 -readconfig /tmp/config
