Platform/OS/Hardware/Device
What are you running the sdk on?

we run our backup app on docker on CentOS Linux release 7.6.1810 (Core).
This app uses (AWS SDK for C++ with Version:1.7.314) to put to or get data from object storage system.

Describe the question

GetObject gets random segment fault. it seems caused by memory allocator.

Logs/output
If applicable, add logs or error output.
