What I don't understand. This part is only executed if p != NULL. Why is p
suddenly NULL inside this function ?
(gdb) p p
$1 = (void *) 0x0
(gdb) p memory
$2 = (struct __rtl_memory_desc_st *) 0x2e5141f8
(gdb) p memory->m_length
$3 = 0
(gdb) p memory->m_blink
$4 = (struct __rtl_memory_desc_st *) 0x0
(gdb) p memory->m_offset
$5 = 0
(gdb) p memory->m_flink
$6 = (struct __rtl_memory_desc_st *) 0x1
Huh ? We free Memory with a lenght of 0 ?
