--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Confirmed.
Appears to have started with r253400.
Happens here:
250 DECL_CONTEXT (decl) = current_function_decl;
within:
245 static void
246 add_decl_as_local (tree decl)
247 {
248 gcc_assert (decl);
249 TREE_USED (decl) = 1;
250 DECL_CONTEXT (decl) = current_function_decl;
251 DECL_CHAIN (decl) = saved_local_decls;
252 saved_local_decls = decl;
253 }
with:
(gdb) call debug_tree (decl)
