>Description:
The build for our in-tree libpcap seems to be broken. This causes failure
of shmif_dumpbus (at least).
The difference seems to be whether ENABLE_REMOTE is defined or not, that is
the struct has an rmt_samp member or not. We define it in CPPFLAGS and I
don't see anything obvious that gets compiled where it is not set.
>How-To-Repeat:
gdb shmif_dumpbus
break pcap_open_dead_with_tstamp_precision
break pcap_dump_open
run -p pcap shmbus
then print sizeof the passed struct pcap when it hits the breakpoints:
(gdb)
4011 p = malloc(sizeof(*p));
(gdb) p sizeof(*p)
$4 = 648
(gdb) p p->rmt_samp
$12 = {method = 0, value = 0}
Breakpoint 1, pcap_dump_open (p=0x40256000, fname=0xffffffffffffdbea "pcap")
at /usr/src/external/bsd/libpcap/lib/../dist/sf-pcap.c:792
792 {
(gdb) n
(gdb) p sizeof(*p)
$7 = 640
(gdb) p p->rmt_samp
There is no member named rmt_samp.
