PVS-Studio warning V579 for Quake3

void Cvar_Restart_f( void ) {
  cvar_t *var;
  ...
  // clear the var completely, since we
  // can't remove the index from the list
  Com_Memset( var, 0, sizeof( var ) );
  ...
}

Most likely this is what should be written here: Com_Memset( var, 0, sizeof( *var ) );

This suspicious code was found in Quake3 project by PVS-Studio static code analyzer.
Warning message is:
V579 The Com_Memset function receives the pointer and its size as arguments. It is possibly a mistake. Inspect the third argument. quake3 cvar.c 763
