AppVerifier(64) breakpoints, exceptions and empty logs?

Question

Hi,
I think this is the correct place to post this, as I cant find Visual Studio Team System Forums->Visual Studio Application Verifier
in the dialog.
I'm looking into a problem with my app running under AppVerifier.
I have Vista Ultimate 64bit OS, a 32bit application I wish to test, and a 64 bit version of AppVerifier.
I tag the app in the verifier, and set the tests I want to perform (Basics).
Run WinDbg, click File->OpenExecutable and run the .exe.
I immediately hit this breakpoint:

ModLoad: 00000000`00400000 00000000`00aee000   App1_Release.exe
ModLoad: 00000000`77c10000 00000000`77d90000   ntdll.dll
ModLoad: 00000000`77db0000 00000000`77f10000   ntdll32.dll
ModLoad: 00000000`75cb0000 00000000`75cf5000   C:\Windows\system32\wow64.dll
ModLoad: 00000000`75c60000 00000000`75cae000   C:\Windows\system32\wow64win.dll
ModLoad: 00000000`75c50000 00000000`75c59000   C:\Windows\system32\wow64cpu.dll
(1184.9c0): Break instruction exception - code 80000003 (first chance)
ntdll!DbgBreakPoint:
00000000`77c54ea0 cc              int     3

& later on in the run :

ModLoad: 00000000`76600000 00000000`76607000   C:\Windows\syswow64\PSAPI.DLL
(1210.814): WOW64 breakpoint - code 4000001f (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
ntdll32!DbgBreakPoint:
77dc0004 cc              int     3

These 2 happen with or without the AppVerifiers modifications, It would be nice to know what they are  about, I'm not sure its essential.
I can hit F5 to continue, the app runs, constantly hitting :

ModLoad: 76860000 76869000   C:\Windows\syswow64\LPK.DLL
(127c.a58): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
ntdll!RtlVirtualUnwind+0x215:
00000000`77c5b745 488b02          mov     rax,qword ptr [rdx] ds:fffffa60`10999b70=????????????????

and so it continues.
The main loop of the app runs uninterrupted, but then starts throwing these exceptions again on exit:

(127c.a58): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.
ntdll!RtlVirtualUnwind+0x215:
00000000`77c5b745 488b02          mov     rax,qword ptr [rdx] ds:fffffa60`10999ab8=????????????????

about 20 times.

Despite all this my Appverifier never seems to generate any more detailed a log than this:

<? xml version="1.0" encoding="UTF-8" standalone="no" ?>

- < avrf:logfile xmlns:avrf =" Application Verifier " >

  < avrf:logSession TimeStarted =" 2009-10-12 : 14:25:28 " PID =" 5216 " Version =" 2 " />

  </ avrf:logfile >

any help would be appreciated,

Cheers
Bree

Hello Bredda,

There is a Visual Studio Application Verifier Forum and I am now moving this post to it so you can get better and quicker response as there are more experts on it.

Thank you for your understanding.
