Maybe I'm missing something but this patch seems to make the assumption
that DECL_ASSEMBLER_NAME is a tree_node. However, it is simply a char *:

>From the patch: 

cgraphunit.c:

+      void **slot;
+      if (!cgraph_inline_hash)
+        cgraph_inline_hash = htab_create_ggc (42, htab_hash_pointer,
+                                             htab_eq_pointer, NULL);
+      slot = htab_find_slot (cgraph_inline_hash,
+                            DECL_ASSEMBLER_NAME (e->callee->decl), INSERT);
+      *slot = DECL_ASSEMBLER_NAME (e->callee->decl);
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

but in cgraph.h we have:

+extern GTY((param_is (union tree_node))) htab_t cgraph_inline_hash;
             ^^^^^^^^^^^^^^^^^^^^^^^^^^
