77	Accessing uninitialized memory in intra prediction PDPC/WAIP	ksuehring		"I got a bug report privately about valgrind reporting the decoder to access uninitialized/not existing memory.

Location: IntraPrediction.cpp line 1039

{{{
          int c = x + y + 1;
          const Pel left = refSide[c + 1];
          const Pel top = refMain[c + 1];

          pDsty[x] = ClipPel((wL * left + wT * top + (64 - wL - wT) * pDsty[x] + 32) >> 6, clpRng);
}}}

**left** seems to point to an unavailable location at some point.

Test setup:

1 frame BQSquare encoded with VTM config QP=32 on Linux/gcc 7.2.1, decoder running with valgrind.

My be an interaction between JVET_K0063_PDPC_SIMP and JVET_K0500_WAIP implementations."	defect	closed	minor	BMS-2.0.1	BMS	BMS-2.0	fixed	Intra, PDPC, WAIP	ksuehring XiangLi fbossen jvet@…
