When we resized the variables (changing the data type too when log
tracing these) as following new version of specs,

      unsigned char file_ID_string[12];
      int32_t x00;
      int32_t x6c;
      int32_t x04;
      int32_t root_tree_node_gap;
      int32_t lowermost_left_tree_node_gap;
      int32_t lowermost_right_tree_node_gap;
      int32_t unknown_long;
      int32_t last_section_page_id;
      int64_t last_section_page_end_address;
      int64_t second_header_address;
      int32_t gap_amount;
      int32_t section_page_amount;
      int32_t x20;
      int32_t x80;
      int32_t x40;
      int32_t section_page_map_id;
      int64_t section_page_map_address;
      int32_t section_map_id;
      int32_t section_page_array_size;
      int32_t gap_array_size;
      int32_t CRC32;
    } fields;
  } _2004_header_data;


then It throws segfault.
Otherwise, It is working fine.

So whether is a problem associated with specifications or something else?
