bt command issue and don't know how to handle section `. relr. dyn' [0x13] #181

Open zslxiu opened 1 week ago

zslxiu commented 1 week ago

The same kernel 4.19 dump, version 7.3.0 uses the bt instruction to not print the call stack, version 7.3.1 uses the bt instruction to print the call stack, and version 7.3.2 uses the bt instruction to exit directly, displaying segment errors (core has been dumped) May I ask why this is? Does this error message not affect load dump? Thank you for your guidance! 'don't know how to handle section `. relr. dyn' [0x13]
