Segmentation fault error

[Fabrizio Regini]

Hi Everybod,

I'm having a problem with a freebsd 6.2 machine.
I just updated to the latest ruby port, and I get this error while  
updating Rails gem:

# gem update rails
Updating installed gems
Bulk updating Gem source index for: http://gems.rubyforge.org/

/usr/local/lib/ruby/1.8/yaml.rb:133: [BUG] Segmentation fault
ruby 1.8.6 (2008-08-11) [i386-freebsd6]

Line 133 is this one:
132     def YAML.load( io )
133         yp = parser.load( io )
134     end


Any clue?

Thanks

Fabrizio
