Segmentation fault

[AlexDiede]

Latest version (d48e71b) segfaults when I'm trying to get a shard iterator for my kinesis app. Here is a minimal code example that shows the issue:

`// excluding includes/using statements for brevity

AWSCredentials creds("ACCESS_KEY", "SECRET_KEY");
ClientConfiguration config;
config.region = Aws::Region::US_WEST_2;
auto client = Aws::MakeUnique<KinesisClient>("kinesis_client", creds, config);

GetShardIteratorRequest request;
request.SetStreamName("stream");
request.SetShardId("shardId-000000000000");
request.SetShardType(ShardIteratorTypeMapper::GetShardIteratorFromTypeForName("LATEST"));
auto response = client->GetShardIterator(request);`

The program is build on Ubuntu 14.04 with the following g++ command:
g++ test.cpp -g -std=c++11 -pthread -I../aws_lib/include -L../aws_lib/lib -laws-cpp-sdk-core -laws-cpp-sdk-kinesis -lcurl -lcrypto

g++ is version 5.3.0.

I built up a debug version and got this stack trace from gdb:

I believe this issue was introduced in commit 9ad3128 as reverting to commit d48e71b (the previous one) resolves the issue.

What's your build command for the SDK?

[AlexDiede]

cmake -DBUILD_ONLY="aws-cpp-sdk-kinesis" -DSTATIC_LINKING=1 <root-sdk-dir>
followed by 'make' for the initial build.
For the debug build I used:
cmake -DBUILD_ONLY="aws-cpp-sdk-kinesis" -DSTATIC_LINKING=1 -DCMAKE_CXX_FLAGS="-g" <root-sdk-dir>

[JonathanHenson]

I'm having trouble reproducing. What happens if you dynamically link?

[AlexDiede]

Result is the same using dynamic linking. Build command: cmake -DBUILD_ONLY="aws-cpp-sdk-kinesis" -DCUSTOM_MEMORY_MANAGEMENT=0 <root-sdk-dir>

Cmake is version 3.2.2 btw.

[qiuyi21]

I have this issue in Windows and can't solve it.
v1.0.164

Reopen this if you still have problem after updating SDK to latest.
