BHO crashes under VM Ware

Question

Hi All,

I have a bit complex scenario. I would try to explain it here.

I am creating a BHO (Browser Helper Object) using ATL/COM under VS2005. VC9 Preciely. My environment is Win-7 and IE-9
This BHO implements IDownloadManager and overrides default FileDownload actions. I have also implemented IBindstatusCallback interface for this.
It also overrides QueryService method and overrides the when it is IID_IDownloadManager.

On download I download all the data and create a file locally and dump it there. 
All this works perfect while I run it on actual Windows, on the other hand as soon as I move my code to run under VM-WARE having same environment "Win-7 and IE-9" it gives me a crash just at the time when my user control leaves the overriden method of IDownloadManager::Download.
I have taken up the stack trace also and it showed me that its crashing under URLMON.DLL. Follwoing is the stack trace I have

=======================================

I can also share the code, but the code is a bit larger, and it may take some time to trim it down. Still I would be willing to do that.
This is an initial information so that if there is someone who really knows this area, I can then share further details with him.

Thanks for the time.

Answer 1

I would suggest the below approach:

1. If it only reproduces in VMWare, it is definitely VMWare issue. I think you should check with VMWare.

2. If it can be reproduced on pure Win7(without hardware virtualization), I would suggest you go to Microsoft Support: http://support.microsoft.com/

 

Of course, if you can share your crash dump together with your symbol files, I will also be very glad to have a glance.

thanks.
