Ah, cool.
Very strange: that stuff doesn't seem to have changed since 8.71.
Anyway, if you want to raise a bug over at bugs.ghostscript.com with the
results of your investigation and assign it to me (chris.liddell (at)
artifex.com), I'll make sure it gets addressed in our repos.
As I said, in the immediate term, disabling the threading is a low risk,
(currently) low impact workaround for this.
Cheers,
Chris
