If the middle logic fail, for example:
if ((post_stats.heap_totalsz_bytes != pre_stats.heap_totalsz_bytes) ||
(post_stats.heap_freesz_bytes != pre_stats.heap_freesz_bytes) ||
(post_stats.heap_allocsz_bytes != pre_stats.heap_allocsz_bytes) ||
(post_stats.alloc_count != pre_stats.alloc_count) ||
(post_stats.free_count != pre_stats.free_count)) {
printf("Malloc statistics are incorrect - freed alloc\n");
return -1;
}
If the above if branch taken, then retest, the rte_malloc_heap_create(__func__) will
failed because already exist the heap.
