Thanks for the simple reproducer! The assertion reproduces for me with qemu-2.1 up to current qemu.git

Hi Max,

Should this bug be cloned in order to get it in qemu-kvm-rhev 7.2.z?

Thanks!
Daniel

Hi Daniel,

I do not know the exact process, but I think it does indeed make sense to have one BZ per target version.


Thank you,

Max
