[Qemu-devel] Crash with pcie-pci-bridge on qemu-system-s390x

[Thomas Huth]

 Hi,

seems like there's a new way to crash QEMU with the pcie-pci-bridge
device (using QEMU master branch of today):

$ s390x-softmmu/qemu-system-s390x -nographic -S
QEMU 2.10.50 monitor - type 'help' for more information
(qemu) device_add pcie-pci-bridge,id=x
Segmentation fault (core dumped)

Does anybody have a clue what might be wrong here?

Backtrace looks like this:
