While running my application under valgrind this is what I'm getting: vex amd64->IR: unhandled instruction bytes: 0x48 0xF 0x5A 0x7 0x48 0xF 0x5A 0x4F vex amd64->IR: REX=1 REX.W=1 REX.R=0 REX.X=0 REX.B=0 vex amd64->IR: VEX=0 VEX.L=0 VEX.nVVVV=0x0 ESC=0F vex amd64->IR: PFX.66=0 PFX.F2=0 PFX.F3=0 ==30824== valgrind: Unrecognised instruction at address 0x66a3b40. ==30824== at 0x66A3B40: ??? (in /opt/intel/composer_xe_2013.4.183/ipp/lib/intel64/libippsy8.so.7.1) the "faulty" instruction is a call to ippsMean_32f function present int the Intel IPP library. Reproducible: Always Steps to Reproduce: Compile the following program: ==================================================================== #include <ipps.h> int main() { float* a = new float[100]; float myResult; ippsMean_32f(a, 100, &myResult, ippAlgHintAccurate); } ==================================================================== g++ valgrind_ipp_bug.cpp -I /opt/intel/composerxe/ipp/include -lipps -L /opt/intel/composerxe/ipp/lib/intel64/ 1. 2. 3.
