vppinfra: loop counter off by 1 in search_free_list()
In search_free_list(), we have this do while loop. do { l--; f_index = h->free_lists[b][l]; f = elt_at (h, f_index); f_size = heap_elt_size (v, f); if ((s = f_size - size) >= 0) break; } while (l >= 0); When (l == 0), we still go back up to execute l--. Then l become -1. The next statement is we index h->free_lists[b][-1]. After that, elt_at() would probably cause a crash in the ASSERT.
