need help with FIR filter

I tried a simple example and ran valgrind on it. It reveals memory corruption. So, I don't understand how to use FIR filter functions. The complete main program is attached, but the problem occurs just constructing the filter.

I'm using:

...

boost::shared_ptr<Ipp8u> buf;
IppsFIRState_64f* pState;

if (ippsFIRGetStateSize_64f (coef.getShape()[0], &bufsize) != 0)
throw std::runtime_error ("fir_double");

buf = boost::shared_ptr<Ipp8u> (new Ipp8u (bufsize*sizeof(double)));
if (ippsFIRInit_64f (&pState, &coef[0], coef.getShape()[0], 0, (Ipp8u*)(buf.get())) != 0)

throw std::runtime_error ("fir_double");
...

I suspect problem is, who allocated memory for pState? I didn't. But nothing in the docs explains this or shows an example.
