Still broken, but I believe we're moving in the right direction.

Major progress, multiply now almost works
...
There's a premature free() somewhere, and I'm not sure why.
Print depends on divide, which is easy, but also on mod and floor (of rationals) which isn't.

OK, my idea that long multiplication is like long addition is wrong.
...
It's still broken, but it's broken because of fundamental misunderstanding which tinkering won't solve.

Much investigation of bignum problems
...
bignum multiply is still not working, but as bignum read and bignum divide depend on it, it's the problem to hit first.

OK, adding bignums works; multiplying bignums does not work.
...
There's no evidence of a bug in reading/printing, because the only way I can currently get a number big enough to trigger the supposed bug is by multiplying, which doesn't work.

Now creating the correct internal bignum representation
...
add_integers returns an integer which by inspection of the internal representation is correct, but the print representation is not correct.
