Ok, thanks for this crucial information! Would backporting be as simple as filing out the class and the single method from Pharo7 and filing in in Pharo6.1 ? (probably not)
I could also move y application to Pharo 7, but sofar I haven’t been able to load Roassal2 in Pharo 7 (32bit). Any information on how to achieve this (on windows)? No Moose 7.0 image with Roassal preloaded available either, AFAIK...

UFFI uses the method source code to map arguments, and if no source code is available, FFI calls cannot be resolved. This is solved in Pharo7 thanks to Vincent Blondeau by embedding argument names into the method (and thus not requiring source code anymore). If you need it, you can take the FFICompilerPlugin class + (RBMethodNode>>ensureCachedArgumentNames) from Pharo7 and try to backport them on your Pharo6 installation.
