my target is compiled by g++, i get this ClassA, its construct method is like:

ClassA::ClassA(void)
public _ZN4ClassAC1Ev
_ZN4ClassAC1Ev    proc near               ; CODE XREF: main+18Ep

push    ebp
mov     ebp, esp
push    edi
push    esi
push    ebx
sub     esp, 7Ch        ; Integer Subtraction
mov     esi, [ebp+arg_0] ; arg_0=this

...

mov     dword ptr [esi], 936FFE8h
mov     dword ptr [esi+8], 9370020h
mov     dword ptr [esi+0Ch], 937003Ch
mov     dword ptr [esi+10h], 9370054h
mov     dword ptr [esi+28h], 9370068h
mov     dword ptr [esi+104h], 937007Ch
mov     dword ptr [esi+120h], 9370094h
mov     dword ptr [esi+128h], 93700A8h
--------------------------------------------------

And Vtable is like,

`vtable for'ClassA
.rodata:0936FFE0 _ZTV4ClassA       dd 0
.rodata:0936FFE4                 dd offset _ZTI4ClassA     ; `typeinfo for'ClassA

why there's more than one vtab there, and two destruct method for each class? i really confuse about it, anybody will help? thanks a lot!
