Hello,
I seem to have discovered a problem in the heap memory allocation and
deallocation operations.
|------------------|----------------------------|
elem padsize newelem
In the malloc_elem_alloc function, when padsize > cache-line (such as 64 bytes)
and padsize < sizeof(struct malloc_elem), the initialization of new_elem will
overwrite and damage the struct malloc_elem information of elem, while setting
the state of new_elem to ELEM_PAD. When releasing new_elem in malloc_elem_free,
it will be converted to elem using RTE_PTR_SUB(new_elem, new_elem->pad), but at
this point, the struct malloc_elem information of elem is damaged.
