ippsMinMaxIndx_8u Behaves differently of different platforms

adi-grossman — Mon, 09 May 2005 23:00:12 GMT

I've noticed that i get bugs on a Pentium4 machine (no HT), it came down to this code segment. buf seems to get written when i call ippsMinMaxIndx_8u.

Ipp8u arr=50; // it's a single element array
Ipp8u buf0=21, minVal=22, buf1=23, maxVal=24, buf2=25;
int minIdx=-11, maxIdx=-12;
ippsMinMaxIndx_8u(&arr, 1, &minVal, &minIdx, &maxVal, &maxIdx);
// At this point: On a Pentium4 machine,
// buf0==0. if ippsw7.dll is removed then buf0==21

Edit: Version:4.1 Build:19Jul2004

Thank You,
Adi Grossman.

Hi,

we tried to reproduce your issue but without success. Could you please prepare a small test case for it?

Regards,

Vladimir
