Details:

Then using memory pools mem_malloc() function will return misaligned memory
adress if the size of enum memp_t is not equal to MEM_ALIGNMENT.
(struct memp_malloc_helper will be the same size as memp_t, resulting in
misaligment after 

/* and return a pointer to the memory directly after the struct
memp_malloc_helper */
  element++;
)
