Crash happens in Intel IPP library, in IppInit() function

Richard_L_1 — Thu, 06 Apr 2017 03:27:07 GMT

Hi Experts,

One of our component module is using Intel IPP library for graphics rendering. However, when we are running stress test benchmark, crashes were observed. It happens in the entry point of this library – the ippInit() function. The crash stack is as follows. We have also have several dump stacks.

Could you please help to take a look? Thanks!

Hi Richard,

Igor_A_Intel — Thu, 06 Apr 2017 15:50:29 GMT

Hi Richard,

You haven't provided enough information:

1) which IPP version do you use

2) OS (guess Windows)

3) arch (ia32 or Intel64)

4) CPU (supported instruction set is enough - SSE42, AVX, AVX2 or smthng else)

5) IPP is linked statically (I guess as I see ippStaticInit) - single or multithreaded version?

6) Did you try to run PX/MX version (just comment ippInit())?

7) And I think that stack dump is not enough to understand the reason of crash; what the kind of crash - access violation, bad instruction ,etc.? which cpu instruction leaded to crash? disasm of several last instructions before crash? and of course the best approach is to provide us some reproducer

Regards, Igor

Hi Igor,

Hi Igor,

Thanks very much for your support!

We will give your access to the environment where this issue is reproduced, you will be able to find every information you need on that. I will update you as soon as the environment is ready.

Thanks,

Richard

Richard, thanks. We will

Hello Chao,

I have a similar issue that my app crashed in ipp library.

If there is a common method to debug this type problem? thanks.

Hi, Richard,

Would you like share the root cause of this issue? Thanks:)

Regards, Chason

Hi Chason, do you a test

Chao_Y_Intel — Mon, 19 Jun 2017 04:45:30 GMT

Hi Chason, do you a test code that could show this problem? From the calling stack, this looks a different problem. The original code was reported for the init() function, but the calling stack from your code is different.

Chao
