DUMP: Date of last level 1 dump: Tue Jan 23 00:10:24 2018
DUMP: Dumping snapshot of /dev/ada0s3a (/) to standard output
DUMP: mapping (Pass I) [regular files]
DUMP: Cache 32 MB, blocksize = 65536
DUMP: mapping (Pass II) [directories]
DUMP: estimated 8222982 tape blocks.

GDB output doesn't appear to be helpful :-(

Reading symbols from /sbin/dump...(no debugging symbols found)...done.

Core was generated by `/sbin/dump 2Lauf - -C 32 /'.
