As far as I can see, these issues are already issues today, as incoming_args in function.h is itself a GTY-ed structure. Note that no index inside cumulative_args_t is required; GC code can test other variables, as in the symtab field of tree_type_common in tree.h. So I think this option is the way to go. Ian
