Ah the failures are in tests I added in the meantime:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=51ce0bf8

Specifically this is now only outputting the first field,
rather than both fields like it should:

printf '%s\n' a:1 b:2 | src/cut -s -d: -f1,2

I'll write a test based on:
(ulimit -v 20000; : | cut -b1-$((2**32-1))) || echo fail
