Subject: bug#18154: 24.4.50; eval-buffer ignores debug-on-error sometimes
Date: Wed, 30 Jul 2014 22:55:07 +0200

Starting Emacs with:

  emacs -Q -nw \
      -eval '(setq debug-on-error t)' \
      -eval '(insert "(defun f () (push))")' \
      -f eval-buffer

only prints this message: 

  Eager macro-expansion failure: (wrong-number-of-arguments (2 . 2) 0)

This is not what I expect; Emacs should enter the debugger instead.
If "(defun f () (push))" is replaced by "(/ 1 0)" then the
debugger pops up as expected.
