Hi all,

In which circumstances might a cCall, registered as follows, invoke
#value on its argument? It happens only in a particular circumstance
(which I'm still pinning down, but seems related to global garbage
collection), which leads me to suspect it's not supposed to happen *at all*.

sdlFlip: aCobject0
    "I set up a flip and return on hardware that supports
    double-buffering, or perform a SDL_UpdateRect on hardware that
    doesn't. My C function call prototype:

    extern DECLSPEC int SDLCALL SDL_Flip(SDL_Surface *screen);"
    <cCall: 'SDL_Flip' returning: #int
        args: #( #cObject )>
