perl 5.22, spamassassin and .db

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
since then upgrade to perl 5.22, I can't run spamassassin with the
bayes filter enabled any more (on NetBSD 7.0/amd64, in case it
matters). The problem is that the bayes_toks file
becomes ridiculously larges (sevral 100s of GB), eventually filling up the
disk's space after a few days (it used to be a few MBs)
the file is reported to be
bayes_toks: Berkeley DB 1.85 (Hash, version 2, native byte-order)

has anyone else seen this ?
I'm running spamassassin from procmail (no spamd).
