No, the header should not be included in the ring buffer. So 
(theoretically) pupa_malloc should not use the region of a header.

Do you compile the code in 64-bit? I tested the code only in 32-bit, so 
it might have problems in a different word size.

I attach my test suite for the memory management to this mail. You can 
replace mm.c with PUPA's (probably with few modifications). You need to 
modify mm.h manually, if you compile it in 64-bit mode. Running test*, 
you can get many, many debug messages. They dump the structures of 
memory buffers, so the messages are not very easy to understand, but 
they will give you some ideas.
