Subject: Problem using YAML/SYCK on Solaris 8

I'm using ruby 1.8.2 (2004-06-28) [sparc-solaris2.8] and yaml/syck
in a daemon script to write alive messages every 10 seconds.
Sooner or later the loop/thread/script ends with one of the following
error messages:

....

9180
9181
/usr/local/lib/ruby/1.8/yaml.rb:340: [BUG] Segmentation fault
ruby 1.8.2 (2004-06-28) [sparc-solaris2.8]

Abort (core dumped)

OR

Exception `NotImplementedError' at /usr/local/lib/ruby/1.8/yaml.rb:340

Here is the simplified source code ...
------------------------
require 'yaml'

i = 0
loop{
  "HelloWorld".to_yaml
  i+=1
  STDERR.puts i
}

uname -a

gcc -v

On Linux there is no problem ;-)


Any suggestions or hints??
