Hello @kavitha123408 ,

Thank you very much for your answer. Could you please provide some more information:

• From which cpp is the utils/Array.h file included from?
• Have you made any changes in how you are compiling the code/could you provide detailed repro steps so we can attempt to reproduce your use case and see if we can see a similar change in behavior between the 2 OS versions?

Thank you very much for your time and collaboration.

Sincerely,

Yasmine

Hello,

Array.h has called from <crypto/Factories.h>

It happens at instantiating of "AWS::Utils::Array<T>Array(const T*,size_t) [ with T= unsgned char;size_t= long unsigned int]

Error is throwing exactly at create new array and initialize it to a raw array. We tried to comment out //m_data(nullptr) and used m_data.reset(nullptr) inside the constructor instead of constructor default variable, This fix went fine .

Are you still running into this build error? I can't seem to reproduce it while trying to build on RHEL with the latest version of the sdk. Here is how I built the sdk:

git clone --recurse-submodules https://github.com/aws/aws-sdk-cpp
cd aws-sdk-cpp
mkdir build
cd build
cmake .. -DBUILD_ONLY="s3" -DCMAKE_BUILD_TYPE=Debug
cmake --build . --config=Debug
cmake --install . --config=Debug

Please let me know if you are still running into the above error when building this sdk.
