I couldn't reproduce it with that code, can you?

Bug #10019: segmentation fault/buffer overrun in pack.c (encodes)

* Backport: 2.0.0: REQUIRED, 2.1: DONE
----------------------------------------
While working with an AWS sample I hit a segmentation fault. The same sample works under 1.9.3. It appeared to be coming from pack.c function encodes. After looking at the source there's a 4K buffer allocated on the stack. I made a minor change to base the buffer length off of the incoming buffer length with a pad and allocate it off the heap. Anyway, after fixing this my code sample runs fine. I'm including a patch file and the sample code.
