PVS-Studio warning V579 for blender

static int imb_read_tiff_pixels(....)
{
  float *fbuf=NULL;
  ...
  memset(fbuf, 1.0, sizeof(fbuf));
  ...
}

Something strange. There's also 1.0 used here.


This suspicious code was found in blender 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. bf_imbuf tiff.c 442
