PVS-Studio warning V512 for MAME

UINT16 m_control_0[8];
#define ARRAY_LENGTH(x)  (sizeof(x) / sizeof(x[0]))

static MACHINE_RESET( tumbleb )
{
  ...
  memset(state->m_control_0, 0,
         ARRAY_LENGTH(state->m_control_0));
}

Most likely this is what should be written here: memset(state->m_control_0, 0, sizeof(state->m_control_0));


This suspicious code was found in MAME project by PVS-Studio static code analyzer.
Warning message is:
V512 A call of the 'memset' function will lead to underflow of the buffer 'state->m_control_0'.  tumbleb.c 2065
