leak memory

[zymerry]

Describe the bug

Aws::Client::ClientConfiguration clientConfig;
            if (!region.empty())
                clientConfig.region = region;
            clientConfig.endpointOverride = endpoint;
            // 30 s
            clientConfig.requestTimeoutMs = 30000;
            clientConfig.connectTimeoutMs = 10000;

            LOG_DEBUG("Aws region: %s, ak: %s, sk: %s, object_name: %s endpoint: %s bucket:%s", region.c_str(), ak.c_str(), sk.c_str(), key.c_str(), endpoint.c_str(), bucket_name.c_str());
            Aws::S3::S3Client s3_client(Aws::Auth::AWSCredentials(ak,sk), clientConfig);

            Aws::S3::Model::PutObjectRequest object_request;
            object_request.WithBucket(bucket_name).WithKey(key_name);

            object_request.SetBody(request_body);

            auto put_object_outcome = s3_client.PutObject(object_request);

以上是我的调用代码，我会在产生云存的线程里一直调用上边的代码。当流入的带宽有增加的情况下，程序占用的内存会有明显增长。但是在带宽下降后，增长的内存并没有得到释放。

说明：
我的程序是持续运行的，在程序开头调用了 Aws::InitAPI(_options);

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

在带宽下降的情况下，占用的内存能够释放掉。

Current Behavior

程序内存会持续性的增加

这个Aws::S3::S3Client s3_client(Aws::Auth::AWSCredentials(ak,sk), clientConfig);可能同样一个配置的，我需要同时创建多个来用来上传文件，涉及到业务问题，所以不能使用一个上传。

在上行带宽增加时，程序内存的占用率增加，在带宽下降时，程序内存使用率持续平衡。等到下次带宽开始增加时，程序内存的占用率又开始增加。周而复始，直至内存耗尽。

Sorry, I don't understand Chinese, but I will do my best with google translate.

Can you make sure that you are making all sdk calls following the correctly format by using {}

#include <aws/core/Aws.h>
int main(int argc, char** argv)
{
   Aws::SDKOptions options;
   Aws::InitAPI(options);
   {
      // make your SDK calls here.
   }
   Aws::ShutdownAPI(options);
   return 0;
}

Also can you update to a newer version of this sdk. 1.7 is very old and there have been many fixes since then.

I use the https protocol to send the data to the endpoint. There is a memory leak problem in multithreaded scenarios.

[jmklix]

Can you provide more details of the memory leak?

• a minimal reproducible sample
• valgrind logs showing the memory leak

I'll mention this again, but upgrading to a newer version of the sdk would be helpful. 1.7 if very old
