Version: syslog-ng 3.3.6.90
Platform: Solaris 10 on SPARC

I've been running syslog-ng 3.0.6 fine for several years.
I've been trying to upgrade to 3.3.latest.
When I upgraded to 3.3.6, syslog-ng would sometimes quit and dump core unexpectedly when I sent it SIGHUP as part of log file rotation.
I figured it might be an ivykis issue perhaps related to https://bugzilla.balabit.com/show_bug.cgi?id=190 ,
so I've just tried upgrading to 3.3.6.90.
But the error I see remains the same.

Log message:

Here's the core dump's backtrace:
