            Bug ID: 1148
           Summary: Getting a segmentation fault for some reason
           Product: nftables
           Version: unspecified
          Hardware: x86_64
                OS: RedHat Linux
            Status: NEW

         Component: nft
          Assignee: pablo at netfilter.org
          Reporter: chokkoretto at gmail.com

Hi!  I've never done this before, but I've checked with my instructor
and other
students and we can't seem to figure this one out.  

Running this
nft add rule ip filter input ip protocol ospf accept
nft add rule ip filter input ip protocol 89 accept

gives this output 
Segmentation fault (core dumped)

using gdb...
(gdb) run add rule ip filter input ip protocol 89 accept
Starting program: /usr/sbin/nft add rule ip filter input ip protocol 89 accept

Program received signal SIGSEGV, Segmentation fault.
0x0000000000411cb9 in payload_expr_pctx_update ()
(gdb) bt
#0  0x0000000000411cb9 in payload_expr_pctx_update ()
#1  0x000000000040f5d6 in expr_evaluate ()
#2  0x000000000040dd8c in stmt_evaluate ()
#3  0x0000000000410eec in rule_evaluate ()
#4  0x000000000042d332 in nft_parse ()
#5  0x0000000000406b4d in nft_run ()
#6  0x000000000040676d in main ()

Assistance appreciated!  Thanks!

--- Comment #1 from Florian Westphal <fw at strlen.de> ---
I guess its a duplicate of bz #1072, I can reproduce this with nft 0.6 from
epel,
but not with 0.7 or git master.
