The patch is the compiler error specific on the compile error on CMVC

SUMMARY:

CMVC has a compiler error on the
const uint64_t OffsetToRaw = is64Bit()
                                   ? toSection64(Sec)->FileOffsetToRawData
                                   : toSection32(Sec)->FileOffsetToRawData;

while  gcc  compiler do not have the problem.
I have to change the code to

  uint64_t OffsetToRaw;
  if (is64Bit())
    OffsetToRaw = toSection64(Sec)->FileOffsetToRawData;
  else
    OffsetToRaw = toSection32(Sec)->FileOffsetToRawData;
