+Subject: [PATCH] readelf: Skip trying to uncompress sections without a name
+
+When combining eu-readelf -z with -x or -p to dump the data or strings
+in an (corrupted ELF) unnamed numbered section eu-readelf could crash
+trying to check whether the section name starts with .zdebug. Fix this
+by skipping sections without a name.
+
+   * src/readelf.c (dump_data_section): Don't try to gnu decompress a
+   section without a name.
+   (print_string_section): Likewise.
