Does this include guile-2.0? That uses the gc library, which seems to require some precautions to be taken on Darwin as regards the loading of dynamic libraries, but I have not heard of problems interfacing with static global objects where those static objects are conventionally allocated rather than GC'ed. In any event, I have not had problems getting guile to work as an optional extension language for a C++ program with linux, from the memory allocation point of view. There are however issues with accommodating guile exceptions, which are basically long jumps, to C++ objects with non-trivial destructors. You have to organize the code so that no guile exception can take such a C++ object out of scope, and no C++ exception can propagate out of a guile dynwind block. Chris
