Oh, it wasn't dumping core; it was just sorting an array containing
undefined elements.

Here's the code I removed :

# Clearing the array we're sorting should be okay.
@a = (1..10);
@b = sort {@a=(); ($a+1)<=>($b+1)} @a;
ok("@b", "1 2 3 4 5 6 7 8 9 10", "clear array being sorted");

As you see this test expects that @b contains elements from @a, even
tough they're freed when @a is assigned the empty list to. (or
something like that)

But I'm not against it if that could work without penalty. (Also:
remember to test how the in-place sort behaves here)
