I get the same crash opening any type of app .net or native, running Windows XP SP3. Seems to happen on the following line, the pointer 43C3E8h contains a null address.

00410D3B  call        dword ptr ds:[43C3E8h]

OK - thanks.  I'm able to get a crash on XP SP2.   Looks like a garbage pointer is getting passed to ntdll!wcslen...

VMMap 2.1 fails to open processes that VMMap2.0 used to open. Sounds like you guys might already be on this. Do you need more information?

Are you running Windows XP by any chance?

Simply to start vmmap.exe and choose any process.

I have a memory dump if it is necessary

I wasn't able to repro the behavior when I made the initial post, but I am able to do so now.
