When trying to set up dovecot, I somehow managed to get a segfault. Trying to
launch dovecot from command line
(simply execute 'dovecot') results in the error message:
Segmentation fault (core dumped)
Trying dovecot -n results in pretty much the same:
# 2.2.9: /etc/dovecot/dovecot.conf
Segmentation fault (core dumped)
Looking at syslog, I see
doveconf[3676]: segfault at 200 ip 00007fbb93c4fcb3 sp 00007fff005b4c10 error 4
in libc-2.19.so[7fbb93c04000+1bc000]
current is 2.2.13
so don't report problems with a outdated version instead
just upgrade - there where bugfixes between 2.2.9 and
2.2.13 in context of segfaults here and there
Thank you. This outdated version is the one packaged in Ubuntu LTS
14.04.1, which I believe I'm not the only one using. Updating the
dovecot packages provided by Ubuntu would certainly help. I understand
that the version I'm using is roughly 9 months old, but then the LTS was
released 3 months ago, why doesn't it include the 2.2.11 or 2.2.12?
And I found the solution in the end, the problem comes from
auth_debug_passwords=yes being the right thing, and
auth_debug_passwords=plain being source of segfault. I don't know where
I got the "plain" value in the first place, but I certainly should have
read more carefully some docs. I also don't know if this was fixed
later, but shouldn't there be a verification on some values of some
variables, when there are limited values to which they can be defined?
Anyway, dovecot is running, all my apologizes for the unwanted spam.
