PVS-Studio warning V512 for MAME

UINT16 m_spriteram16[0x1000];
UINT16 m_spriteram16_buffered[0x1000];

static WRITE32_HANDLER( deco32_buffer_spriteram_w )
{
  deco32_state *state =
    space->machine().driver_data<deco32_state>();
  memcpy(state->m_spriteram16_buffered,
         state->m_spriteram16, 0x1000);
}

This is what should have been written here: 0x1000 * sizeof(UINT16).


This suspicious code was found in MAME project by PVS-Studio static code analyzer.
Warning message is:
V512 A call of the 'memcpy' function will lead to underflow of the buffer 'state->m_spriteram16_buffered'. deco32.c 706
