Then I agree with Phoebe's excellent answer over on the other thread:

My slight hesitation was that if the warrants were exercised to purchase "new and improved" company stock (which might be substantially equivalent to the crappy old company stock) within 30 days, the wash sales may continue to roll.

Since everything was disposed of in the same year you don't have to wait and see if anyone can come up with a valuation for the warrants.
