I have found a bug in ippsPhase_64fc,

where should I report it?

Dear Customer:

You could report the problem here. Could you tell me what's version of IPP you are using, how about your system environment & what kind of error (error message) you are facing? and could you also provide a test case if possible that we could reproduce. Thanks.

Best regards,
Fiona

This is the code that crashes

This is the code that crashes on Ipp version 2017.0.098

Hi Eyal,

Igor_A_Intel — Mon, 05 Dec 2016 12:42:50 GMT

Hi Eyal,

Could you be more specific - please add 2 more lines of code and provide an output, please:

const IppLibraryVersion* lib;

lib = ippsGetLibVersion();

printf("major = %d\n",lib->major);

printf("minor = %d\n",lib->minor);

printf("majorBuild = %d\n",lib->majorBuild);

printf("build = %d\n",lib->build);

printf("targetCpu = %s\n",lib->targetCpu);

printf("Name = %s\n", lib->Name);

printf("Version = %s\n", lib->Version);

printf("BuildDate = %s\n", lib->BuildDate);

I've tried your example on Win32 and don't see any issues - so I need OS, arch, static or dynamic linking, mt or st, etc. - this all info will be clear from the ippsGetLibVersion()

regards, Igor

It is linux 64bit

It is linux 64bit

The output is:

major = 2017
minor = 0
majorBuild = 0
build = 52494
targetCpu = y8
Name = ippSP SSE4.2 (y8)
Version = 2017.0.0 (r52494)
BuildDate = Jul 16 2016

dynamic linking

dynamic linking

Dear customer,

Dear customer,

I could reproduce your problem by using g++ compiler, but no error with icc compiler. We will investigate on it. Thanks.

Best regards,
Fiona
