It's quite possible that I overlooked that. But from what I recall those symbols are statically allocated and always marked by the GC through the literal frames, so they should not need to be explicitly marked as persisted. Remember, symbols are kept alive by any reference to them, so even if they're not marked as persisted, as long as something refers to them they will stick around. > - Shouldn't C_COLLECT_ALL_SYMBOLS defined in chicken.h instead of all > makefiles? > Or do you anticipate that this may be undesirable on some platforms? I think the patch was _removing_ the option, because it is no longer optional. Cheers, Peter
