PVS-Studio warning V511 for ReactOS

void
Mapdesc::identify( REAL dest[MAXCOORDS][MAXCOORDS] )
{
  memset( dest, 0, sizeof( dest ) );
  for( int i=0; i != hcoords; i++ )
    dest[i][i] = 1.0;
}

The 'dest' object is simply a pointer. Value [MAXCOORDS][MAXCOORDS] in the square brackets indicates to the programmer that he is working with an array of MAXCOORDS x MAXCOORDS items.
But it is not an array of items which is passed into the function - it is only the pointer.
So, the sizeof(dest) expression will return value 4 or 8 (the size of the pointer in a 32-bit/64-bit system).
This is what should have been written here: Mapdesc::identify( REAL (&dest)[MAXCOORDS][MAXCOORDS] )

This suspicious code was found in ReactOS project by PVS-Studio static code analyzer.
Warning message is:
V511 The sizeof() operator returns size of the pointer, and not of the array, in 'sizeof (dest)' expression. glu32 mapdesc.cc 95
