Will check whether I have the commit you mentionned

and with the really latest that works fine, sorry for the noise

All seem to work fine: ```lisp COMMON-LISP-USER>> (defun foo (x y) (declare (single-float x y)) (ext:with-float-traps-masked () (/ x y))) FOO COMMON-LISP-USER>> (foo 1.0 0.0) Debugger received error of type:...

on mac

This might not happen in all installations, e.g. drmeister does not seem to observe this

#936 also happens here

* Does not seem to happen with MPS. * Since neither Bike nor drmeister seem to have the same issue, it might depend on the bdw-gc version being installed. *...

```lisp (load "~/quicklisp/setup.lisp") (time (ql:quickload "cffi" :verbose t)) (time (ql:quickload "cffi-tests" :verbose t)) (cffi-tests::run-all-cffi-tests) -> .... 29 out of 323 total tests failed: FUNCALL.CHAR, DEFCFUN.CHAR, DEFCFUN.NOOP, DEFCFUN.BFF.1, DEFCFUN.BFF.2, CALLBACKS.CHAR, CALLBACKS.LONG,...

now gives: `(#:|4| #:|3| #:|2| #:|1| #:|0|) NIL`

Second evaluation comes from: ```lisp (defun run-all-cffi-tests () (append (run-cffi-tests :compiled nil) (run-cffi-tests :compiled t))) ````
