I can see that there is the orc_header symbol and data also in a vmcore, so maybe it can be read easily: crash> whatis orc_header const u8 orc_header[20]; crash> rd -8 orc_header 20 ffffffffb718ef94: fe 5d 32 bf 58 1b d6 3b 2c a9 a5 c6 5b a5 a6 25 ... ffffffffb718efa4: ea b3 fe 24 but it's a hash, not a version number, how are you going to use this? Does crash have to have all historical hash values? all of format changes do not affect crash's unwinder though. Thanks, Kazu
