+Subject: [PATCH] PR 33455 SEGV in vfinfo at ldmisc.c:527
+
+A reloc howto set up with EMPTY_HOWTO has a NULL name.  More than one
+place emitting diagnostics assumes a reloc howto won't have a NULL
+name.
+
+	PR 33455
+	* coffcode.h (coff_slurp_reloc_table): Don't allow a howto with
+	a NULL name.
+
