#1 0x0000000000c34951 in tree_is_indexable (t=<result_decl 0x7ffff6e810f0>)

(gdb) call t->decl_minimal.context
$1 = <tree 0x0>
it seems the decl doesn't have DECL_CONTEXT set despite being a RESULT_DECL.
(gdb) p function
$2 = <function_decl 0x7ffff6e7af00 _Z3foov.resolver>
target bug:
/* Build result decl and add to function_decl. */
t = build_decl (UNKNOWN_LOCATION, RESULT_DECL, NULL_TREE, ptr_type_node);
DECL_ARTIFICIAL (t) = 1;
DECL_IGNORED_P (t) = 1;
DECL_RESULT (decl) = t;
which fails to set DECL_CONTEXT (t) = decl.
