So the external call does not happen and the fall-back code executes. That explains it. It might be nice if FFI calls could be made to happen, or at least to have a more informative error message, such as "Primitive not executed by the debugger" rather than "Unable to find function address."

I often (not always??) find that using the Debug-it command and debugging into an external call (FFI) leads to a false claim of "Unable to find function address." Stepping over the call works; stepping into it make it look like it fails.
I am curently using a 1.1 RC2 image and the 4.0.3 vm on Ubuntu. I cannot easily move the offending code to Windows, nor do I particularly care to do so (feels good<g>), and FFI is fairly uncommon in Squeak/Pharo.
Can anyone else tinker with this to see if it is real?
IIRC when you're using the debugger, primitives are not evaluated.
