When I run (rt:do-test 'cffi-tests::callbacks.stdcall.1), I get this printed:

That's good, it means the test passed.
When I try:
(asdf:oos 'asdf:load-op :cffi-tests) (asdf:oos 'asdf:test-op :cffi-tests)
Clozure crashes to its kernel debugger.
Can you get a backtrace? Hopefully one of the tests is triggering the same bug you're experiencing with GLUT which I suspect is unrelated to stdcall. -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/

The transcript is in the attached file "latest-cffi-test.txt". Greg

So it seems like CCL crashes in the CALLBACKS.QSORT test (in cffi/tests/callbacks.lisp) somewhere within the call to qsort(). I would guess there is some bug related to callbacks. Try this: (ccl:defcallback qsort-callback (:address a :address b :signed-int) (let ((x (ccl:%get-signed-long a)) (y (ccl:%get-signed-long b))) (cond ((> x y) 1) ((< x y) -1) (t 0)))) (defun test-callbacks-with-qsort () (ccl:%stack-block ((array 40)) (loop for i from 0 and n in '(7 2 10 4 3 5 1 6 9 8) do (setf (ccl:%get-signed-long array (* i 4)) n)) (ccl:external-call "qsort" :address array :signed-int 10 :signed-int 4 :address qsort-callback :void) (loop for i from 0 below 10 collect (ccl:%get-signed-long array (* i 4))))) -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/

(defun test-callbacks-with-qsort () (ccl:%stack-block ((array 40)) (loop for i from 0 and n in '(7 2 10 4 3 5 1 6 9 8) do (setf (ccl:%get-signed-long array (* i 4)) n)) (ccl:external-call "qsort" :address array :signed-int 10 :signed-int 4 :address qsort-callback :void) (loop for i from 0 below 10 collect (ccl:%get-signed-long array (* i 4)))))
That seems to work! The output is in the attached file, good-cffi-results.txt Does this mean cffi can be patched again? Regards, Greg

We figured out how to make the test trigger the bug. I've attached said test case to the Trac ticket started by Greg at <http://trac.clozure.com/ccl/ticket/527#comment:2>. -- Luís Oliveira http://student.dei.uc.pt/~lmoliv/

I've attached a transcript of the Trac ticket containing the backtrace and registers after the qsort loop call. http://trac.clozure.com/ccl/attachment/ticket/527/transcript.txt Greg

After picking up the 12226 win32 binary that was just checked in by Gary, the problem is resolved. The QSort callback test and (cl-glut-examples:gears) both work. Well done! And thank you! Regards, Greg
