+    Re: tekhex object file output fixes
+
+    Commit 8b5a212495 supported *ABS* symbols by allowing "section" to be
+    bfd_abs_section, but bfd_abs_section needs to be treated specially.
+    In particular, bfd_get_next_section_by_name (.., bfd_abs_section_ptr)
+    is invalid.
+
+            PR 32347
+            * tekhex.c (first_phase): Guard against modification of
+            _bfd_std_section[] entries.
+
