Summary: ERb throws SystemStackError on Solaris 10

Initial Comment:
Several files are attached to replicate an error that I originally saw using Rails ActiveRecord fixtures and traced to ERb on Solaris.  I can only replicate this on "ruby 1.8.4 (2005-12-24) [sparc-solaris2.10]" so far, x86 machines execute the code fine.  The example program is "a.rb":

##begin
require 'yaml'
require 'erb'

#def erb_render(fixture_content)
#  ERB.new(fixture_content).result    
#end

yaml_string = ""
Dir["./**/*.yml"].select {|f| test(?f,f) }.each do |subfixture_path|
puts subfixture_path
yaml_string << IO.read(subfixture_path)
end

### This throws an error
#yaml = YAML::load(erb_render(yaml_string))

zz = ERB.new(yaml_string)
zz.result  # (erb):5005: stack level too deep (SystemStackError)

##end



The output using the included files is:

  ./protocols.yml
  ./samples.yml
  ./sample_types.yml
  ./sexes.yml
  (erb):5005: stack level too deep (SystemStackError)

If the last item in 'samples.yml' is removed ("samples_4492:") then the error is not thrown.
