Segfault dovecot 2.2.9

[Simon Gareste]

Hi all,

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]

I tried but couldn't find the core dump anywhere on the server. Any help 
on this would be appreciated too.

I (trying to ) run it with postfix, on an Ubuntu 14.04 (Linux 
mail2.arturia.com 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 
UTC 2014 x86_64 x86_64 x86_64 GNU/Linux), brand new server. What 
troubles me even more is that I just set up successfully another mail 
server a week ago, with the same configuration (diffing the conf 
folders) except for log or mailbox paths (driver and stuff are the same).

In the google search I've done, I saw some stuff about openssl: both 
servers are running 1.0.1f, since one is running fine, I guess this is 
not the culprit.

One difference I noticed between the two servers is that on the failing 
one, there is no /var/run/dovecot. I presume this folder and its files 
are created once dovecot is launched, so that's why it's not present, 
and is only a symptom of the failure, not a cause?

Thanks for your help, and please tell me what other information I could 
provide to help.
