All fixed now by v5.23.2-75-g9ae0115 (along with v5.23.2-74-gebc643c
that makes it check at run-time on DEBUGGING builds, pp_assign's
compile-time assumptions).

Well actually AnyEvent still fails 2 test for me, but it failed them prior
to the bisected commit, so I assume its fixed as far as this issue goes.
