[syslog-ng] syslog-ng 3.3.2 seg faulting sending message via tcp

[Patrick H.]

Syslog-ng 3.3.2 (obtained from 
http://www.balabit.com/downloads/files?path=/syslog-ng/sources/3.3.2/source) 
is segfaulting when it tries to send a message to a TCP destination. I'm 
asking here instead of a bug report because I didnt see a 3.3.2 release 
announcement, so not sure if this is the final build or not.

Anyway, gdb backtrace shows:
Program received signal SIGSEGV, Segmentation fault.
