Thanks, I have a fix, but the usage of STR_NOFREE seems dangerous from str_new_static

Bug #10942: Suspected memory leak

----------------------------------------
There seems to be memory leaking when calling Aws::SQS::Client#receive_message in Ruby 2.2.0 and 2.2.1. I am not very good at memory/object allocation profiling in Ruby, but I know for sure that there must be some issue, because my SQS workers run out of memory every day.

See gist https://gist.github.com/quezacoatl/7657854f371edcb5d8e6 to reproduce. I've added output.txt for my output for different Ruby versions. Ruby 2.1.2 works fine. I'm sorry that I cannot pinpoint the exact issue. Perhaps somebody with better profiling skills can do this?
