Fails to build tests on latest nightly

[Ryman]

pub static mut freelist: [&'static mut [u8]; 16] =
    [&mut [], &mut [], &mut [], &mut [], &mut [], &mut [], &mut [],
    &mut [], &mut [], &mut [], &mut [], &mut [], &mut [], &mut [],
    &mut [], &mut []];

At one point, the macros used in tests/lib.rs expand to the above, which is allowed on stable and beta, but seems to be denied on nightly. You can try it here: https://is.gd/9tUBN8

This might be related to rust-lang/rust#33130

I can't reproduce the problem: maybe it was a regression on nightly?

[Ryman]

I think it's fixed now but I hadn't had a chance to test the fix since it landed in nightly, glad to hear the fix worked!

Thanks so much for reporting this and following through on the fix (!)
