.NET Debugging: How to enable GCStress in Win-7?

Question

I am debugging a GC heap corruption and came to the step where I want to try running the program under WinDbg+PageHeap+AppVerifier+GCStress.

I found at http://social.msdn.microsoft.com/Forums/en/clr/thread/0fcb5bb1-0cd8-40e4-96d9-f0cb8b6cdbdf[^] that I can enable GCStress like this:

<small>reg.exe add "HKLM\SOFTWARE\Microsoft\.NETFramework" /f  /v HeapVerify  /t REG_DWORD  /d 1  <br />
reg.exe add "HKLM\SOFTWARE\Microsoft\.NETFramework" /f  /v StressLog  /t REG_DWORD  /d 1  <br />
reg.exe add "HKLM\SOFTWARE\Microsoft\.NETFramework" /f  /v GCStress  /t REG_DWORD  /d 3  <br />
reg.exe add "HKLM\SOFTWARE\Microsoft\.NETFramework" /f  /v FastGcStress  /t REG_DWORD  /d 2</small>

[ trying this method - takes the program forever to launch, I deleted the last two entries from the registry to have it work, probably something is wrong with the approach itself. ]

or at http://social.msdn.microsoft.com/Forums/en/clr/thread/33920b39-690c-42c8-b04a-0f1f7176835a[^] described the other method:

<br />
    <small>(DWORD) StressLog = 1  <br />
    (DWORD) LogFacility = 0xffffffff  <br />
    (DWORD) StressLogSize = 65536</small>

Which way is correct or is there another correct way?

I read that itz a known issue which will be fixed in the next version of the .NET Framework.

Itz recommeded to disable background GC setting in the application configuration file, as the work around.

XML

<configuration>

    <runtime>

        <gcConcurrent enabled="false"/>

    </runtime>

</configuration>

Yes, that worked for me. But the question still remains - how to enable GCStress.
