Describe the bug

Some test cases in aws-cpp-sdk-core-tests fail with assertion errors related to Aws::Utils::TempFile when building aws-sdk-cpp using MinGW (gcc 11.4.0) on Windows 11. The failures output errors such as assertion failures and file errors.

Expected Behavior

All test cases should pass and the compilation procedure should complete successfully.

Current Behavior

Test cases related to Aws::Utils::TempFile fail with assertion errors (see previous logs for details):

• AWSConfigFileProfileConfigLoaderTest.TestCredentialsFileCorrupted
• AWSConfigFileProfileConfigLoaderTest.TestConfigFileLoad
• AWSConfigFileProfileConfigLoaderTest.TestCredentialsBlankSpace

Reproduction Steps

1. Build the project with:

   cmake .. -G "Ninja" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DAWS_SDK_WARNINGS_ARE_ERRORS=off
   ninja
   

2. Run the test suite.

Possible Solution

The issue has been resolved by the me and a pull request has been created #3551
Failed test cases are all related to Aws::Utils::TempFile.
The root cause is in Aws::FileSystem::CreateTempFilePath(), Macro L_tmpnam_s.
