The PDB's often do not contain the proper info to determine where the locals are at every particular moment in time, so you sometimes have to look at the disassembly to figure out what the fcn is doing. For your particular case, its likely that a local variable does not exist at 0x47f. 'dv /V' will tell you where the debugger is looking for your locals.

I am running Windows XP X64. e.g. 0:000> dt pstro Local var @ 0x47f Type _STROBJ* ???? Memory read error 000000000000047f I just get these "memory read errors". The driver is built using "build" using the checked environment. I can step thru the code, look at registers and call stacks, but I am unable to view locals. I have tried using the Visual Studio 2005 beta 2 debugger as well - same type of problem. Using the "!sym noisy" command I can see that the driver PDB is being loaded. It appears to be a result of the AMD64 build. I can debug the 32 bit build of the driver fine on 32 bit Windows XP, using Windbg or Visual Studio debugger . Any ideas?

memory could not be read" With Windows, you never know what crazy error message will one day pop up and scare the heck out of you! One error message that I have seen on a clients machine recently was: Instruction at 0x000 referenced memory at 0x000. The memory could not be read. Wow! What the heck does that even mean!? Well, just like most Windows errors, it can be a LOT of stuff. This error can be caused by bad memory, a bad CPU, older drivers, hardware conflicts, and a bunch of other stuff! With this type of error, you basically have to try a bunch of things and see http://www.osronline.com/showThread.cfm?link=77623 if something works. Also, think logically about each solution. For example, if your computer is brand new, then you probably don’t have bad memory. Method 1 – Increase Virtual Memory One reason you might be getting this error is if your virtual memory settings are very low. You can right-click on My Computer, go to the Advanced tab, and click on Settings under Performance. Then click on the Advanced tab again under http://helpdeskgeek.com/help-desk/instruction-at-referenced-memory-could-not-be-read/ Performance Options and click the Change button under Virtual memory. Read my previous article on how to optimize the page file size in order to set the value to the appropriate setting for your computer. Restart the computer and see if the problem goes away or not. Method 2 – Uninstall Buggy Software Another reason this may occur outside of possible hardware problems is if you have buggy software installed or visit a website that has buggy code. If you’ve recently installed some program that is not Adobe, Microsoft, Google, or from some other big and reputable company, try to uninstall it and see what happens. A lot of times it can even be popular software that just has bugs in it. Also, this referenced memory error happens in software programs related to firewalls, anti-virus, anti-spyware and the like. If you’re using something like that, try uninstalling and see if the problem goes away. If you have anti-virus software or any type of real-time Internet traffic scanning software, make sure to disable it and see if the problem goes away. If a program is scanning web traffic, you can get the referenced memory error. Method 3 – Update drivers and install latest patches Depending on your hardware, you may be getting the error beca

Windows, however, works if the error read error box is not closed. The 'Memory address could not be read' error happens because of issues related to hardware problems in RAM memory or if the hard disk reaches its optimum level. If the PC is affected with viruses or if the OS update fails to work properly, these type of errors are generated. The management of applications run by the system read error at must also be checked to avoid this issue. Check if the RAM is working properly Managing applications Hard disk and virtual memory status Your PC is infected Windows Update is not working properly Reinstall Windows Update: Repairing Windows update Verifying Windows Update and BITS services parameters: Re -Register Windows Update DLL files: Add RAM memory: Windows may prompt you with the following error message: svchost.exe -- application error the instruction at "0x745f2780" reference memory at "0x00000000". the memory could not be 'read' And on diagnosing the problem: Faulting application svchost.exe, version 5.1.2600.2180, faulting module msi.dll, version 3.1.4000.2435, fault address 0x00******.
