Please apply

  (setq debug-on-error t
        debug-on-signal t
        debug-on-quit t)

before the next test. Then, when Emacs hangs, you could try from a shell

# kill -FPE <emacspid>

Don't ask me why, but sometimes Emacs comes back with the FPE signal,
and you get a backtrace. This I would like to see, because then I could
protect that code with-local-quit and friends.

Best regards, Michael.
