igdumdim64.dll shouldn't call SetUnhandledExceptionFilter()

[bvg]

Hi Intel developers,

After hours of investigations, I've realized that the reason why my software, which is using Google breakpad, is no more reporting crash information seems to be due to the "igdumdim64.dll" DLL (version 30.0.101.1338), coming from the installation of the Intel HD Graphics drivers, that calls the system function SetUnhandledExceptionFilter().

Calling this function results in the handling function installed by breakpad not being registered as an exception handler anymore, and therefore prevents my software from being able to generate crash reports.

It is generally admitted that DLLs shouldn't call SetUnhandledExceptionFilter() for this exact reason: it would interfere with the parent process functionalities.

Could it be possible to remove call(s) to this function from this DLL and maybe instead use  __try/ __except statements ?

Hello Jean,

Thank you for providing me with a link to the Developer Zone, but I'm not sure about where I should post my message.

I'm not looking for help about my software, but wanted to report what I consider a bug in the Intel HD Graphics drivers code which is impacting my software.

There are similar posts on this forum about issues with those drivers (see for instance https://community.intel.com/t5/Graphics/igd10iumd64-dll-may-crash-or-freeze-for-D2D-render/m-p/1341957), so I thought it would be the proper place.

Maybe I just need to tag my post with a "GPU driver" label ?

Hi,

Thank you very much for looking into this issue, since I suspect it might also affect other softwares that rely on the SetUnhandledExceptionFilter() function to report application crashes.

If it could be of any help, here is an excerpt of the call stack of a test program, where I modified breakpad's code to put a hook on "kernel32.dll" so a RedirectedSetUnhandledExceptionFilter() function is called instead of the system SetUnhandledExceptionFilter() function, and a minidump is written:

We were investigating the same issue as the original author of this thread. We found that our application crash reporter doesn't work on some machines. We traced the issue to your drivers. You are breaking all 3rd party apps that runs on machines with Inter driver and they can't use Crash Reporting. Please consider removing this code.

[MWolff]

Same here, can this please be reopened? Or better yet, fixed in the driver code?

To other developers affected by this: I managed to find a workaround for the Qt application we are working on. The backtrace there was something like this:

By overriding the QApplication::notify (a global event filter could work too), we can get notified about the first PlatformSurface. After handling this, I'm now blindly re-applying the call to SetUnhandledExceptionFilter from breakpad, to ensure its handler is taking precedence over the Intel GPU driver handler. This seems to work in early testing, and we can continue to install the event handler early, minimizing the time frame where no crash reports would be caught by us.

Hope that helps!

But one way or another, the Intel GPU driver code really needs to be fixed, it's clearly bad/wrong to call this windows API in such a central dll, totally breaking crash reporting tools!
