Hello to everybody,
first of all: thanks a lot for your hard work and for this nice piece
of software!
After many search about the following SIGSEGV, I decide to post the backtrace
and I hope to have avoided duplicated thread.
The problem arise after I enable clucene fts. I tryed the clucene ports version
(I am using OpenBSD) and a fixed version from github
(Blue-Rocket/clucene::feature/pod) which contains FreeBSD fixes and
others memory leak patches, but the problem persists.
I built either dovecot-* and clucene-core with -g and the following
logs are taken
from that version.
Maybe, I can do more debugging but I don't know how; some ideas?
thanks a lot
