           Summary: nftables - Set - define core dumps
           Product: nftables
           Version: unspecified
          Platform: x86_64
        OS/Version: Ubuntu
            Status: NEW
          Severity: major
          Priority: P5
         Component: nft

I m trying to define a set in file

define ip_set = {192.168.1.2, 192.168.2.3}
add rule filter output ip daddr $ip_set counter

nft -f files/set_anand
Segmentation fault (core dumped)

On looking into the core file , it appears to be a issue with symbol_bind()
where both &sym->list, &scope->symbols to list_add_tail seem to
point
the same ..


Core was generated by `nft -f files/set_anand'.
Program terminated with signal 11, Segmentation fault.
