I found that the symbol __cxa_throw has been moved to __AUTH_CONST and it has found multiple non-lazy pointer symbol tables (__auth_got and __got). But the implementation we had looked at in the last section found __got. So I updated the implementation to look into segment __AUTH_CONST in section __auth_got

Any update on this? I have been depending on dynamically rebind __cxa_throw in the loaded libraries to catch the original stack trace, implementation explained here https://github.com/facebook/fishhook The problem is after iOS 14.5 it's not working anymore because I cannot find the Mach-O section where "lazy symbol pointer table" is found, and thus not able to rebind __cxa_throw_. I have discussed this in a lap in WWDC21, it looks related to a change called "Chained fixups" that I'm still searching for. If the bug reported here is fixed I won't need that workaround at all.
