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:
