In up to date master branch: (i) emacs -Q (ii) Enter the following into buffer *scratch*: (defun E+->E@+ (elt op) (cond ((eq op '+) (setcar elt '*)) ((eq op '+\?) (setcar elt '*\?)))) (defconst foo-elt '(+\? . "foo")) (E+->E@+ foo-elt '+\?) . (iii) With point in the defun, M-x compile-defun. (iv) Evaluate the defconst. (v) Evaluate the E+->E@+ form. (vi) M-: foo-elt. It's value is unchanged from its declaration. It should have been changed to (*\? . "foo"). This is a bug. (vii) M-x disassemble RET E+->E@+. Instead of working, this gives the error message: Optimizer error: missed tags (((TAG 2) TAG 4) ((TAG 1) TAG 3)) . This is a bug. (viii) (Optional) Evaluate the defun form with C-M-x, and evaluate the E+->E@+ form. M-: foo-elt. This shows the expected value, (*? . "foo"). At a guess, the symbols with the \? in their names have something to do with the bug.
