I've posted a new SqueakFFIPrims plugin to my idisk v 1.4.0b1
http://www.smalltalkconsulting.com/squeak.html
Follow the link to the idisk, then to the experimental directory for SqueakFFIPrims.v1.4.0b1.bundle.zip
The Sophie/TK4 team has been busy working on Quicktime based Books, however it confirmed the issue that the Mac Carbon VM interpreter() thread is not thread safe with the UI for some FFI calls. Therefore in this version of the SqueakFFIPrims logic we now callback to the VM to ask it to schedule the FFI call on the UI thread. This adds a bit of overhead (people are welcome to measure) however it avoids the issue of having your FFI collide and crash with some window managment or quicktime movie task on the main thread.
The update are on the SVN server
FFI users should confirm I've not broken anything, also you should test the 3.8.10b15 VM for unix binary library interfacing to confirm that feature works. Note the use of the plist XML entry to tell the VM only to load from the Plugins, resources, or /System/ Framework/ directory. You must turn that feature OFF in order to refer to libraries in /bin/ lib etc.... plus trying 80 other combinations of names and paths hunting for the FFI module in question.
I'll note I did build a Squeak Mac Carbon VM where interpreter() runs on the main UI thread and polls the OS event services for pending events, however when the macintosh menus are choosen, why the VM stops running. Not a nice feature, perhaps this is not fixable so I'm not migrating to this implementation yet.
