The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.
If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.
Thank you and sorry for the inconvenience.
** Changed in: qemu
Status: New => Incomplete

Title:
fatal error: float32nan on QEmu 3.1
Status in QEMU:
Incomplete
Bug description:
Docker throws float32nan errors when running alpine container on a
CentOS 7.6 ppc64le Distro VM, when using Fedora 30 Host qemu 3.1. I
Compiled qemu 2.11.2 on the Fedora 30 and using this qemu-system-ppc64
we don't see the error. Even using qemu 3.1 and machine 2.11 we still
get the same issue.
Nothing changed on the OS level on the two runs. just the qemu-system-
ppc64 used to run the virtual machine.
Docker on CentOS 7: docker.ppc64le 2:1.13.1-96
Running with qemu 2.11.2 behavior and machine 2.11:
