Crash Debugging Win32 Application

Question

I'm spending lot of time doing crash debugging of Win32 apps. One thing i'm very curious to know about is, How to find whether any address belongs to stack / heap or program code section. Is there any windbg/ollydbg plugin available for this purpose? Or I've to to it manually from memory map? Ex:

0:000> r
eax=00930264 ebx=008e0000 ecx=41414592 edx=00930000 esi=41414141 edi=008e0441
eip=00407289 esp=0012fae0 ebp=0012faf4 iopl=0         nv up ei pl nz na pe nc
cs=001b  ss=0023  ds=0023  es=0023  fs=0038  gs=0000             efl=00010206
MyApp+0x7289:
00407289 8b1437          mov     edx,dword ptr [edi+esi] ds:0023:41cf4582=????????
0:000> u eip
MyApp+0x7289:
00407289 8b1437          mov     edx,dword ptr [edi+esi]
0040728c 8b4c3704        mov     ecx,dword ptr [edi+esi+4]
00407290 57              push    edi
00407291 e89ae8ffff      call    MyApp+0x5b30 (00405b30)
00407296 897d14          mov     dword ptr [ebp+14h],edi
00407299 5f              pop     edi
0040729a 85c0            test    eax,eax
0040729c 741e            je      MyApp+0x72bc (004072bc)

In this case i wanna know which register pointing to which section (code/stack/heap )so that i can proceed further to the root cause.

Thanks in Advance.
