Hello All,

               I have fixed this problem for temporarily. I got core dump in
wiretap/file_access.c file in lin 684.

> gboolean wtap_dump_close(wtap_dumper *wdh, int *err)

Parameter passed to this function at run time when we close or stop
tethereal :

>  wtap_dump_close(0x0, 0x7f7f0d44)

So, the problem comes in the following line:

> if (wdh->subtype_close != NULL) {

I have just included the following line to prevent core dump.

        if( ! wdh )
        {
                return ret;
        }

Before modifiying:

wiretap/file_access.c

   680  gboolean wtap_dump_close(wtap_dumper *wdh, int *err)
   681  {
   682          gboolean ret = TRUE;
   683
   684          if (wdh->subtype_close != NULL) {

After modifiying:

wiretap/file_access.c

   680  gboolean wtap_dump_close(wtap_dumper *wdh, int *err)
   681  {
   682          gboolean ret = TRUE;
   683
   684          if( ! wdh )
   685          {
   686                  return ret;
   687          }
   688
   689          if (wdh->subtype_close != NULL) {


Now it works fine.

Thanks,
Durai.
