Ah, I just remembered why I wanted to build manually in the first place;
that means I can now properly check newer qemu versions.
I've confirmed master does work properly even with --disable-pie.
The first commit that does not segfault with this build is this one:
dd55885516 ("linux-user: Rewrite non-fixed probe_guest_base")
OTOH there have been many other changes to linux-user/elfload.c in the
mean time, so it's not easy to backport, and there might be other
indirect requirements; I've not taken the time to untangle that.
I've also had a quick look at the launchpad[1] that introduced
--disable-pie, and agree with you; the only difference seems to be
'file' output of statically linked -> (now) static-pie linked and
foreign containers work just as well with the static-pie version.
I see you've removed the option in newer debian[2], so as far as debian
bookworm is concerned I'm still of the opinion that removing
`--disable-pie` is probably the easiest way forward unless someone
knows of a good reason we need to keep it.

(But, once again I see no rush on this; this can easily wait until you
get back from your trip. I have much more pressing things to do which
means I obviously had to find something to procrastinate on :-) )
Thanks,
