+       * symbols.c (struct local_symbol): Update comment.
+       (resolve_symbol_value): For resolved symbols equated to other
+       symbols, verify that the referenced symbol is not a local_symbol
+       before accessing sy_value.  Don't leave symbol loops during
+       finalize_syms resolution.
+       * testsuite/gas/all/assign-bad-recursive.d: New test.
+       * testsuite/gas/all/assign-bad-recursive.l: Error output for test.
