[Pharo-dev] OSSubprocess 0.2.5 fails in Pharo 6.1 64 bits (macOS)

When trying the simple example (ls -la /Users) in Pharo 6.1 64bit you get a talkback because ExternalAddress integerAt:put:size:signed: fails using 'primitiveFFIIntegerAtPut' in module 'SqueakFFIPrims' Something to do with OSSubprocess not accommodating 64 bit pointers perhaps? Same code works fine on 32bit version.
