When will the crash be fixed?
I used #84 code and it worked.But it's not merged into the main branch,so can I use it?
you can use it !
crash reason:
int mprotect(void *address, size_t size, int protect);
function Require address alignment at all iOS version(Not only iOS 14.5). apple doc- The memory mapped to the __DATA_CONST section is readable and writable before iOS 14.5; but in iOS 14.5 maybe readwrite,maybe readonly。

Thanks for the fix!! In case anyone else is using fishhook on the Mac, you will need this fix for macOS 12.

@cfxiao can you supply detail codes? which func been hooked?
from fishhook.
@leirenbaobao it seems that he hook the dispatch_sync.
And I try to hook malloc / realloc get same crash report.
I'm pretty sure the iOS 14.5 beta at newer phones such as iPhoneXs, has change the memory offset of core library.

@biosli I tested some funcs. some crashes. what puzzle me is that even offset changed normal dynamic binding still work without hook.maybe it's nothing to do with offset.
from fishhook.
I found some case that vm_protect return KERN_SUCCESS , but memory don't set VM_PROT_WRITE success. like mprotect method
oldProtection = get_protection(rebindings);
is wrong, It save struct rebindings_entry *rebindings
memory protection. We should save section protection.
I commit code that oldProtection = get_protection((void *)trunc_address);
.
and I found a problem when program set same section protection in multithread(iOS 14.5).
