Indeed, you shouldn't call FOREIGN-FREE on pointers to memory not allocated by FOREIGN-ALLOC. You should be able to (defcfun free ...) and use that. > In my code below, a new 'sdl-version' struct is returned by > (sdl-mixer-cffi::linked-version). The error seems to occur when I try to > free the struct at the end of the function using foreign-free. However, under SBCL FOREIGN-FREE is equivalent to free() -- not sure about CCL. According to SDL_Mixer's documentation, Mix_Linked_Version() returns a const pointer, so it seems that the bug here is that you're trying to free() non-malloc()ed memory.
