I see that you are running in QEMU. Do you have KVM enabled? Can you retest on bare metal?

comment:2 by Coldfirex, 14 months ago

From my understanding it is. My hypervisor is Proxmox which uses QEMU and KVM.

Sorry, I dont have anything atm to run bare metal.

I just noticed the "value: deadbeef", so this is really a use-after-free.

stress-ng --sem-sysv 128

reproduces the problem quickly.
