Can you create an issue on https://gitlab.com/qemu-project/qemu/-/issues
and attach the static binary you built, that way we can reproduce your
problem.

Thanks!

Ubuntu 23.04, - I guess it is qemu 8.0, no?  8.0 has a few issues with
linux-user, some of them were there in 7.2 too.  And some of that has
additional patches (coming from upstream most of the time).

Please note also that there are quite a few fixes has been made to both
qemu 8.0 and 7.2 stable series, including linux-user area.
