That last situation is really totally unsupported and never was. By the way, I
don't know if you noticed already, but it doesn't work for many, many, reasons
outside sizes of containers. It's totally broken everywhere. The linker should
also warn about that, I think we have a PR, it's a much more general issue,
warn when linking together stuff built passing ABI-incompatible switches.
