I seem to be getting mixed messages from savecore(8)

This is running a system based on head at r354689. (I realize that it
claims r354207; there was an "issue" with respect to git notes &
refs....)
Evidence:
test_host# savecore -v -v -C /dev/nda0p5
checking for kernel dump on device /dev/nda0p5
mediasize = 17179869184 bytes
sectorsize = 512 bytes
First dump headers:
Dump header from device: /dev/nda0p5
Architecture: amd64
Architecture Version: 2
Dump Length: 247502187
Blocksize: 512
Compression: gzip
Dumptime: Sun Dec 8 22:05:20 2019
Hostname: test_host.ix.nflxvideo.net
Magic: FreeBSD Kernel Dump
Version String: FreeBSD 13.0-CURRENT #0 r354207+6722509e5333-c729675(release-2
019Q4.3.1): Wed Dec 4 11:43:57 PST 2019

Last dump headers:
Dump header from device: /dev/nda0p5

Dump Length: 247502187
Blocksize: 512

A dump exists on /dev/nda0p5
test_host# savecore -v -v -m3 --libxo json /var/log/coredumps /dev/nda0p5
unable to open bounds file, using 0
checking for kernel dump on device /dev/nda0p5
test_host# echo $?
0
test_host#
So: If I understand correctly, "savecore -C" detacts that a dump exists
on the cited device, but invoking savecore to actually ... save ... the
dump does not actually do that.
Any suggestions for expressing my request in a way that savecore is a
bit more likely to accept?
Thanks!
Peace,
david
