qemu crashes with assertion error `!mr->container' failed

[R.Nageswara Sastry]

Re-production steps:
git clone today's qemu git tree (4th Oct 2017)
./configure --target-list=ppc64-softmmu && make -j 8

Run the device-crash-test from scripts folder, seeing the following error

I think this should be fixed by this patch here:
https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg06696.html
("hw/pci-bridge/pcie_pci_bridge: properly handle MSI unavailability case")

With the mentioned patch not seeing the Abort.

# ppc64-softmmu/qemu-system-ppc64 -S -machine bamboo,accel=kvm -device pcie-pci-bridge
gtk initialization failed

Thanks!!
