Strange qemu behavior on sparc64


i am using netbsd9.0/sparc64.

When i try to run emulators/qemu from pkgsrc-2020Q1 or pkgsrc-2020Q2,
all components do nothing. They are also not visible with high load on

For example i run qemu-img or qemu-system-sparc without any
parameters. It should come back with a message telling me an error or
missing parameters i guess...but nothing happens. The terminals just
sits there and nothing will happen.

ps shows:
root 21589  0.0  0.1 70432 6464 pts/1  I+    8:16PM 0:00.09 qemu-img

The same happens with gdb qemu-img. After "(gdb) run" it does nothing.
I have to press ctrl-c to interrupt it and then i will get:

bash-5.0# gdb qemu-img

(gdb) run

Program received signal SIGINT, Interrupt.
0x0000000042952cb4 in ___lwp_park60 () from /usr/lib/

So the process is sleeping or parked. The same happens with all qemu components:

(gdb) run
Starting program: /usr/pkg/bin/qemu-system-sparc
Program received signal SIGINT, Interrupt.
0x0000000044352cb4 in ___lwp_park60 () from /usr/lib/

What is going on here? Can anyone reproduce this on sparc64 or has a
clue how to fix it?
