wow64!_TEB32 not found

I am trying to analyze a wow64 process dump. The issue is memory leak, so I need to check the heap. I am referring to this article to analyze the dump:

0:000> .load wow64exts

0:000> !sw
Switched to 32bit mode

0:000:x86> !heap -s

Can not find wow64!_TEB32, so can not go ahead. Is there any body whole can help on this?


First, make sure that your symbols are set up correctly, usually by doing

.symfix c:\symbols

Usually, for 32 bit applications, a 32 bit dump should be taken, if you don't want to debug the WOW64 layer itself.

However, in your case (concerning the !heap commands), you can just repeat the steps in the 32 bit version of WinDbg, which also runs on 64 bit Windows and which can open 64 bit dumps.
