    dumpcap -i wlan0 -w /tmp/dumpcaptest.pcapng

and

    tcpdump -i wlan0 -w /tmp/tcpdumptest.pcap

(yes, ".pcap" - libpcap doesn't yet support writing pcap-ng files).  Do those
two separately; you can remove /tmp/dumpcaptest.pcapng once you've either
determined that dumpcap fails at 2^31-1 bytes or happily goes past 2^32 bytes.

If "everything" includes libpcap, it probably hasn't changed in the past few
hours, so that shouldn't be necessary.
