Do you have the output of `qemu-system-x86_64 -version`, and more
information on how your binary was built?

Output of `-machine help` and `-machine pc,help` would be useful
to debug it, too.

I can't reproduce it here.=C2=A0 I've tested both qemu.git master (commit cb5ed407a1dd) and v5.2.0-rc (commit 3d6e32347a3b).
