+Subject: [PATCH] x86: Guard against corrupted PLT
+
+There should be only one entry in PLT for a given symbol.  Set howto to
+NULL after processing a PLT entry to guard against corrupted PLT so that
+the duplicated PLT entries are skipped.
+
+	PR binutils/22170
+	 * elf32-i386.c (elf_i386_get_synthetic_symtab): Guard against
+	 corrupted PLT.
+	 * elf64-x86-64.c (elf_x86_64_get_synthetic_symtab): Likewise.
