My code crashes with static library but not dynamic library

[RoyZhang2022]

I am having a crash for AWS-SDK-CPP on macOS(Monterey 12.6) when I run my test which uses AWS SDK CPP. The crash stack is listed below. It crashes at the Aws::InitAPI() for the first time call. I build SDK by myself. This problem only exists when I linked the SDK static library, not dynamic library. Is it a SDK bug?

   552 	            return s_configManager->GetConfig(Aws::Auth::GetConfigProfileName(), key);
   553 	        }

--The steps I used to build AWS SDK. If I set -DBUILD_SHARED_LIBS to "ON", there is no any problem for my test.

git clone --recurse-submodules -b "1.9.79" "https://github.com/aws/aws-sdk-cpp.git"
cd aws-sdk-cpp
mkdir install
mkdir build
cd build
cmake ../ -DCMAKE_INSTALL_PREFIX="../install" -DTARGET_ARCH="APPLE" -DCMAKE_BUILD_TYPE="Debug" -DBUILD_ONLY="core;sts;timestream-query" -DCUSTOM_MEMORY_MANAGEMENT="OFF" -DENABLE_TESTING="OFF" -DBUILD_SHARED_LIBS="OFF" -DCPP_STANDARD="17"
make -j 4
make install

I have figured out it is my problem. I have linked to my dynamic library which links to AWS SDK static libraries, while at the same time my test still links to AWS SDK static libraries. That means I links to AWS SDK static libraries twice. So it causes this problem.
