The caller of buffer_init() has to provide the space.

(Select Modules, then IO Utility Library, Buffer Management to
see the related documentation.)
In your example file, just have a look at how buf[] is defined:
#define XMPL_FRAME_SIZE (40)
...
uint8_t buf[sizeof(buffer_t) + XMPL_FRAME_SIZE];
So, it should be clear that 40 bytes are allocated for the actual
frame contents.
