Intermittent SIGSEGV in Aws::S3::S3Client::PutBucketAcl()

[kailascohesity]

Describe the bug

I am intermittently seeing segmentation fault while calling Aws::S3::S3Client::PutBucketAcl(). The issue was consistent/very frequent when using slightly older release [aws-sdk-cpp-1.9.319]. The issue has become intermittent since I moved to release [aws-sdk-cpp-1.9.328].

Here's the stack trace (trimmed few initial calls as it's part of proprietary code) - 210660 *** Aborted at 1661395837 (unix time) try "date -d @1661395837" if you are using GNU date *** 210661 PC: @ 0x7ffb1da49aa0 (unknown)

Expected Behavior

The API should complete consistently, without any crash/faults.

Current Behavior

The SDK is crashing with segmentation fault.

Reproduction Steps

Calling the same API PutBucketAcl() may reproduce the issue. I am seeing the issue with two independent binaries.
