I was able to recreate this, eventually. I deleted my earlier comment where I failed to reproduce it - my method of extracting a bitstream from the list of numbers was flawed.

First, I greedily requested 10,000 random numbers from xkcd with a script. These numbers are here so nobody need re-commit my deed: https://gist.github.com/tonyb486/0da38e7575071f241551d14101a...

Then, I filtered out all numbers 2048 and above so that I just had 11 bits of entropy from each number from [0,2048). I converted that to a stream of binary in ASCII, 11 bits per random number.

I fed that list of 78100 bits into STS, as 100 streams of 780 bits. It segfaulted, but it had already written out some results:

Delightful.
