Hello,
I've just upgraded from www/squid 3.5.27_1 to www/squid-devel 4.0.22.
Everything seems to works well except when "rotating logs".
Well, in fact I don't need to really rotate logs, I just have to use "squid -k
rotate" or "kill -USR1 <squid-pid>" (from
http://www.squid-cache.org/Doc/config/logfile_rotate/ ) and Squid will crash
leaving:
"Dec 18 19:59:01 host kernel: pid 7965 (squid), uid 100: exited on signal 6
(core dumped)
Dec 18 19:59:01 host squid[2003]: Squid Parent: (squid-1) process 7965 exited
due to signal 6 with status 0
Dec 18 19:59:01 host squid[2003]: Squid Parent: (squid-1) process 52870
started"
in /var/log/messages and I am getting a coredump.
Anyway, Squid continues to work, so users don't see anything.
I've recompiled Squid with DEBUG=on and with gdb on the coredump file I am
getting:

It crashes here:
https://github.com/squid-cache/squid/blob/v4.0/src/comm.cc#L428 but now I don't
know what else to try.
I am running Squid 4 on NanoBSD 11.1-RELEASE-p6, so I don't know if this bug is
present on a "normal" FreeBSD or Linux.
My Squid is compiled with security/libressl-devel 2.6.3.
In my Squid's config file, I have "logfile_rotate 0" because I am managing the
rotation with newsyslog.
Can someone try "squid -k rotate" or "kill -USR1 <squid-pid>" to see if it can
be reproduced?
I've just tried again with www/squid 3.5.27_1 and it doesn't crash at all
(exact same configuration, only difference is the Squid version).
Best Regards,
Olivier
