Using a lighttpd 1.4.26 web server freshly built from current pkgsrc
on NetBSD 5.0.2 (i386/xen) to serve https traffic, the lighttpd
process occasionally segfaults.  Here is a backtrace:

  Core was generated by `lighttpd'.
  Program terminated with signal 11, Segmentation fault.

The only SSL related options used in the lighttpd.conf file are
"ssl.engine" and "ssl.pemfile".

Perhaps this is related to the Apache segfaults discussed in the
thread beginning with the message


Set up a lighttpd web server with SSL.  Serve traffic.
