PVS-Studio warning V512 for Snes9x

struct ICheat
{
  uint32  address;
  uint32  new_val;
  uint32  saved_val;
  int     size;
  bool8   enabled;
  bool8   saved;
  char    name [22];
  int format;
};

struct SCheat
{
  uint32 address;
  uint8   byte;
  uint8   saved_byte;
  bool8  saved;
};

void RamWatchEnableCommand(....)
{
  ....
  struct ICheat cht;
  ....
  ZeroMemory(&cht, sizeof(struct SCheat));
  ....
}

Most likely this is what should be written here: ZeroMemory(&cht, sizeof(struct ICheat));


This suspicious code was found in Snes9x project by PVS-Studio static code analyzer.
Warning message is:
V512 A call of the 'memset' function will lead to underflow of the buffer '& cht'. ramwatch.cpp 1199
