When QC_MDDT is defined, the following variables allocated in source\Lib\TLibCommon\TComRom.cpp are not freed in the decoder. Some of them are not freed in the encoder.

UInt *scanOrder4x4[9];
UInt *scanOrder4x4X[9];
UInt *scanOrder4x4Y[9];
UInt *scanOrder8x8[9];
UInt *scanOrder8x8X[9];
UInt *scanOrder8x8Y[9];
UInt *scanStats4x4[9];
UInt *scanStats8x8[9];

UInt *scanOrder16x16[NUM_SCANS_16x16];
UInt *scanOrder16x16X[NUM_SCANS_16x16];
UInt *scanOrder16x16Y[NUM_SCANS_16x16];
UInt *scanStats16x16[NUM_SCANS_16x16];

UInt *scanOrder32x32[NUM_SCANS_32x32];
UInt *scanOrder32x32X[NUM_SCANS_32x32];
UInt *scanOrder32x32Y[NUM_SCANS_32x32];
UInt *scanStats32x32[NUM_SCANS_32x32];

UInt *scanOrder64x64[NUM_SCANS_64x64];
UInt *scanOrder64x64X[NUM_SCANS_64x64];
UInt *scanOrder64x64Y[NUM_SCANS_64x64];
UInt *scanStats64x64[NUM_SCANS_64x64];

In TMuC 0.5 encoder, some of these variables are released in Void TAppEncTop::encode(). I think we'd better release them in Void destroyROM() (TComRom.cpp). Otherwise, we have to keep duplicate code in both encoder and decoder. To fix this problem, maybe we can put the following code at the end of Void destroyROM() and remove the related code in Void TAppEncTop::encode().

#if QC_MDDT ADAPTIVE_SCAN

for(ipredmode=0; ipredmode<9; ipredmode++)
{

delete scanOrder4x4[ipredmode];

delete scanOrder8x8X[ipredmode];
delete scanOrder8x8Y[ipredmode];
delete scanStats4x4[ipredmode];
delete scanStats8x8[ipredmode];
