On this, I am quite sure I have managed to crash wine on linux by dyn.load() an updated version of a DLL of the same name with win32 R in wine. It is obviously a useful thing to be able to change the source, re-compile it, and load a new version into R, so that's why I did it, I think. (and it does work with native R on linux). Genuine windows may or may not crash, but I don't usually sit in front of windows for development...
