Check compiled v. interpreted versions.

Comment (by mevenson):

The exact conditions to trigger this problem are not simple, as the following works in both interpreted and compiled modes

{{{ ;;file:///opt/local/share/doc/lisp/HyperSpec-7-0/HyperSpec/Body/m_defi_3.htm

(defun lastguy (x) (car (last x)))

(define-setf-expander lastguy (x &environment env) "Set the last element in a list to the given value." (multiple-value-bind (dummies vals newval setter getter) (get-setf-expansion x env) (let ((store (gensym))) (values dummies vals `(,store) `(progn (rplaca (last ,getter) ,store) ,store) `(lastguy ,getter)))))

(defun use-lastguy () (let ((a `(1 2 3 4))) (setf (lastguy a) 42) a)) }}}

following works […]

My current working hypothesis is that things involving macros aren't being expanded at the correct time.

Triaged back to failure in abcl-1.1.1, so this is not the result of recent damage.

Comment (by charmon):

This is also true for define-modify-macro. Both issues are fixed by the most recent 2 commits on my setf-and-modify-eval-when branch: https://github.com/slyrus/abcl/commits/setf-and-modify-eval-when

Any chance of getting this committed soon? Then we can revert the corresponding CFFI patch and get the rest of the ABCL support for CFFI committed.

Comment (by mevenson):

In testing your patch, ran into an issue that may or may not have been a result of not doing a complete recompilation. I'll get back to this later today.

Unfortunately for CFFI, until we get a release of abcl-1.4.0 or (abcl-1.3.2) with this patch, I wouldn't recommend changing the CFFI patch, as almost no users will have had a chance to update. I don't know where the compromise lies: since we have to appease the CFFI maintainers, and the problems with DEFINE-SETF-MODIFY affect the code shared with other Lisp implementation, I don't expect them to want to "dirty" the code with the necessary hack for the broken ABCL. But on the other hand, if CFFI doesn't use the ugly version of the DEFINE-SETF-MODIFY code, the usage of CFFI will break for all ABCL users not running from abcl-1.4.0-dev sources. This week is busy for me, so I would realistically guess that I could make a release of abcl sometime in the next two weeks.

After a recompilation of ABCL from scratch, this patch does indeed seem to resolve the underlying issues. I'm running more of the test suite to ensure we haven't broken anything else, afterwards I'll commit Cyrus' patch. Thanks!
