Steps to reproduce:
- Enable CLucene FTS in Dovecot;
- Open mailbox with MUA;
- Search for message with any text;
- IMAP session crash.
OS: Gentoo Base System release 2.6
Version:
FTS: dev-cpp/clucene-2.3.3.4-r6
IMAP: net-mail/dovecot-2.3.2.1
LIBC: sys-libs/musl-1.1.21
Dovecot FTS config:
plugin {
fts = lucene
fts_lucene = whitespace_chars=@. normalize no_snowball
fts_autoindex=yes
fts_autoindex_max_recent_msgs=80
fts_index_timeout=90
}
