After we upgraded to protobuf-3.25.3, it always crashes in abseil code. Could you help check?
we dlopen two dynamic libraries(libView-TsdrClient.dylib, libView-ScannerRedirClient.dylib) in different threads. However, it always jump in dead lock and then crash.
If it is not a bug, could you give us some suggestions?
Also, Could you tell what's this used for since I can not find where is is invoked? absl::lts_20240116::flags_internal::FlagRegistrar<std::__1::basic_string<char, std::__1::char_traits, std::__1::allocator>, true>::OnUpdate(void (*)()) && + 36 (flag.h:779)
