>Description:
With a ruby (ruby18-base) built without native pthread
(RUBY_USE_PTHREAD=no in /etc/mk.conf), tDiary (diary/blog
writing tool, http://www.tdiary.org) doesn't work at all.

If a ruby is built with the native pthread, tDiary works well.

The symptom is that it always dumps core when an http server
invokes its top page CGI (index.rb).  This can be repeated
manually from shell.

I got a traceback from its core:

>How-To-Repeat:
Download tDiary from http://www.tdiary.org (2.0.2 or 2.1.4 is fine)
and extract the package, then

% ruby index.rb

will always dump core.
