PVS-Studio warning V579 for samba

static bool _reg_perfcount_init_data_block(....)
{
  smb_ucs2_t *temp = NULL;
  ....
  memset(temp, 0, sizeof(temp));
  ....
}

Most likely this is what should be written here: sizeof(*temp).


This suspicious code was found in samba project by PVS-Studio static code analyzer.
Warning message is:
V579 The memset function receives the pointer and its size as arguments. It is possibly a mistake. Inspect the third argument. reg_perfcount.c 945
