Hi Kazu I am thinking of comparing the hashes to figure the ORC format in use. This would be similar to how the drgn tool does things: https://github.com/osandov/drgn/commit/0d6438d994a4c46c4a08b73a98c637f5bc040ce8. Similar to how you printed the orc_header using the crash command line, if you can point out how to do so in a programmatic fashion, that would be great. Thanks!
