--- Comment #3 from Michael Osipov <michaelo@FreeBSD.org> ---
I don't understand this crash, there is no code in JVSC which calls:

Can someone load the dump into LLDB and show the backtrace? I can directly
commit a fix into commons-daemon if we can work out a patch. I don't have a
aarch64 to work on this myself.
