Platform: Mac OS,. 10.15 & Mac OS 11.x ( arm64)
Compiler: AppleClang 12.0.0.12000032
Mac OSX SDK: 11
I link libprotouf.a to my shared libary (dylib). The dylib is compiled
using -fsanitize=thread -O1 but protobuf is compiled as normal ( without
any sanitizer flags )
When i run in thread sanitizer, i get SEGV and here is a sample callstack

What could be causing this issue? we never had this issue with our previous
protobuf version compiled the same way 3.21.12 using the same clang
compiler version as universal binary. Any advise?
