It looks as if
ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/i386/base43.tgz
is somehow broken, I can't untar/ungzip it properly on a i386 which
runs snapshot from 22. May. Fetched it twice from the primary site
this morning, as it was not available from the secondary mirrors yet:

The other .tgz files look ok.
