[flow-tools] Intermittent Header Bug in ftio.c ; recommended fix?

[Dutky, Steve]

Please note varible flags referenced before it is initialized:

void ftio_header_print(struct ftio *ftio, FILE *std, char cc)
{
  struct ftiheader *fth;
  struct ftmap_ifname *ftmin;
  struct ftmap_ifalias *ftmia;
  char agg_ver, agg_method;
  char *agg_name;
  char fmt_buf[32];
  u_int32 flags, fields;
  u_long period;
  int n, streaming2;

  fth = &ftio->fth;

  fields = ftio->fth.fields;
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  streaming2 = (flags & FT_HEADER_FLAG_STREAMING);
  if (flags & FT_HEADER_FLAG_PRELOADED)
    streaming2 = 0;

  if (fields & FT_FIELD_HEADER_FLAGS)
    flags = ftio->fth.flags;
  else
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
...
from ftio.c


results in most of the time:
$ flow-stat -p <./flow/2002/2002-06/2002-06-04/ft-v05.2002-06-04.091501-0400
>

but sometimes:

$ flow-stat -p <./flow/2002/2002-06/2002-06-04/ft-v05.2002-06-04.091501-0400
