FYI: The issue shows up on previous versions of GCC compiler as well, as early
as 4.9.2 (have not tried earlier versions). 

Also if the "buffer" in main is declared as a static uint8_t array, the issue
does not show up. For some reason it shows up only when buffer is a pointer as
shown in the source snippet.
