I think there is a bug in symbol lookup since this commit : 05eff01e89ee345e70acdbebc9c3778766b76ee2.
        if (p->deps) for (i=0; p->deps[i]; i++) {
-               sym = lookup(s, h, p->deps[i]->syms,
-                       p->deps[i]->hashtab, p->deps[i]->strings);
+               sym = lookup(s, h, p);
                if (sym && sym->st_value && (1<<(sym->st_info&0xf) & OK_TYPES))
                        return p->deps[i]->base + sym->st_value;
        }

this should be :

        if (p->deps) for (i=0; p->deps[i]; i++) {
-               sym = lookup(s, h, p->deps[i]->syms,
-                       p->deps[i]->hashtab, p->deps[i]->strings);
+               sym = lookup(s, h, p->deps[i]);
                if (sym && sym->st_value && (1<<(sym->st_info&0xf) & OK_TYPES))
                        return p->deps[i]->base + sym->st_value;
        }

Boris
