--- Comment #4 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
Started with r256685.
The problem is in dump_generic_node:
case FUNCTION_TYPE:
case METHOD_TYPE:
...
if (TYPE_NAME (node) && DECL_NAME (TYPE_NAME (node)))
dump_decl_name (pp, TYPE_NAME (node), flags);
(gdb) print node
$21 = <function_type 0x7fffef652dc8 printfn_t>
(gdb) print node.type_common.name
$22 = <identifier_node 0x7fffef654730 printfn_t>
TYPE_NAME is an IDENTIFIER_NODE, whereas we're expecting a DECL_P, and we ICE.
