Does that actually happen? It shouldn't. A symbol node contains the C
name of the symbol, but you should never have a SYM_NODE that points
to another SYM_NODE, it always points to some actual type (ie ptr,
whatever).
So the rule should be that the node can have specific information
about that particular named symbol (so: name, array size, modifiers,
address space, initializer etc), and then the node->ctype.base_type
should point to a non-NODE symbol describing the base type.
But maybe I forget some special case. Things like 'typeof() can be
complicated, but we should be peeling things off so that we only ever
have one level of SYM_NODE.
