lib/util/util.c: In function ‘dump_data_block16’:
lib/util/util.c:503:40: error: ‘%04zX’ directive output may be truncated
writing between 4 and 16 bytes into a region of size 15
[-Werror=format-truncation=]
  503 |         snprintf(tmp, sizeof(tmp), "%s[%04zX]", prefix, idx);
      |                                        ^~~~~
