Yesterday, we tracked down a serious issue in 64 bit FFI. After giving up with our own code, we made a fresh start with the latest base image and OSWindows. We were finally able to figure out what went wrong with two simple tests that were failing in 64 bit that worked correctly in 32 bit. FFIConstantHandleType externalType is the wrong size After confirming that and making it work, we were told that a number of FFI fixes were done by Nicolas and Eliot in Squeak that did not get integrated in Pharo. Applying the changes from the latest Squeak FFI resolved the problem, and a few that we were unaware of. Stephan
