If the recipe to reproduce is this:

  emacs -Q
  M-: (setq max-lisp-eval-depth 32768) RET
  M-x load-theme RET modus-vivendi RET

then I cannot reproduce this with the current master branch: I get the
theme loaded with no crash.

Are you using the modus-vivendi theme from the master branch?  Do you
see the problem in "emacs -Q"?  The above discussions point to a bug
that was closed, but it sounds like the problem only happens in your
customized sessions, so we still need to understand what is the recipe
for reproducing the problem.
