QEMU v5.2.0: object_new_with_type: assertion failed: (type != NULL)

[Bharat Bhushan]

Hi All,

I am using QEMU version "v5.2.0" and getting below error when running on arm64

$ qemu-system-aarch64 --version

ERROR:../qom/object.c:711:object_new_with_type: assertion failed: (type != NULL)
Bail out! ERROR:../qom/object.c:711:object_new_with_type: assertion failed: 
(type != NULL)

Running GDB give below information.
Is this something known.

(gdb) run
