ippsResamplePolyphaseFixedInit_32f

Can someone enlighten me on why the call to ippsResamplePolyphaseFixedInit_32f results in a

0xC00000005: Access violation

int ssize;
int height = 3;

              ippsResamplePolyphaseFixedGetSize_32f( (int)SigIn->numberOfSamplesPerSecond() , _sampleRate, 128, pSizeOut, &ssize, &height, ippAlgHintFast );

               pState1 = (IppsResamplingPolyphaseFixed_32f*)ippsMalloc_8u(ssize);
               pState2 = (IppsResamplingPolyphaseFixed_32f*)ippsMalloc_8u(ssize);
               int inRate = (int)SigIn->numberOfSamplesPerSecond() ;
               IppStatus stsCode1 = ippsResamplePolyphaseFixedInit_32f( inRate , _sampleRate, 128, 0.9f, 9.0f, pState1, ippAlgHintFast );


           }

ippsResamplePolyphaseFixedGetSize_32f( (int)SigIn->numberOfSamplesPerSecond() , _sampleRate, 128, pSizeOut, &ssize, &height, ippAlgHintFast );

Fixed

pSizeOut is wrong this should be ssize

ippsResamplePolyphaseFixedGetSize_32f( (int)SigIn->numberOfSamplesPerSecond() , _sampleRate, 128, &ssize, &len, &height, ippAlgHintFast );
