I guess this means a bug in DB_File.so or Perl. No matter how badly
Spamassassin is written it must not be able to produce a segfault.
Is DB_File.so an OpenBSD-specific implementation of database?
This segfault was produce by sa-learn -D --sync and the last debug message it
printed was "[25545] dbg: bayes: tie-ing to DB file R/O
/home/clock/.spamassassin/bayes_seen"
Backtrace from core dump and the output from sa-learn -D --sync follows.
