Comment (by nomeata):

 The cause does not seem to be tied to a particular part of the code:
 Luckily, `doFile` has a very plain pipeline. The symptoms disappear when I
 stop at processing `with_ccs` and appear if I go until `with_synth_2`. But
 if I read `with_css` from a file instead of calculating it and only do the
 `synth_2` call, the result also becomes deterministic. Tricky.
